[PATCH v4] Staging: olpc_dcon: Replace timespec with ktime_t

by Ksenija Stanojevic

Struct timespec will overflow in year 2038, here it will not cause an overflow because it is used with timespec_sub, but still has to be removed as part of y2038 changes. Replace it with ktime_t.

[PATCH 0/5] y2038 conversion for ntp/pps and sfc driver

by Arnd Bergmann

When trying to build a kernel with time_t commented out, I found that the ntp subsystem still relies on timespec for its pps handling. This series addresses this and converts all the code to use timespec64 instead, step by step. There is one device driver that interacts with this code directly (rather than only through the ptp subsystem), so I have to convert that driver at the same time. The patches should ideally stay together as a series, but they do span multiple subsystems, so I'm also looking for the right person to merge them. Please review. Thanks, Arnd Arnd Bergmann (5): ntp/pps: use timespec64 for hardpps() ntp/pps: replace getnstime_raw_and_real with 64-bit version ntp: use timespec64 in sync_cmos_clock ntp/pps: use y2038 safe types in pps_event_time net: sfc: avoid using timespec drivers/net/ethernet/sfc/ptp.c | 30 +++++++++++++++--------------- drivers/pps/kapi.c | 4 ++-- include/linux/pps_kernel.h | 16 ++++++++-------- include/linux/timekeeping.h | 4 ++-- include/linux/timex.h | 2 +- kernel/time/ntp.c | 16 ++++++++-------- kernel/time/ntp_internal.h | 2 +- kernel/time/timekeeping.c | 14 +++++++------- 8 files changed, 44 insertions(+), 44 deletions(-) -- 2.1.0.rc2

[PATCH] ceph: fix message length computation

by Arnd Bergmann

create_request_message() computes the maximum length of a message, but uses the wrong type for the time stamp: sizeof(struct timespec) may be 8 or 16 depending on the architecture, while sizeof(struct ceph_timespec) is always 8, and that is what gets put into the message. Found while auditing the uses of timespec for y2038 problems.

[PATCH] Staging: fbtbt: Replace timespec with timespec64

by Ksenija Stanojevic

struct timespec will overflow in year 2038, so replace it with timespec64. And replace functions that use struct timespec, timespec_sub with timespec64_sub and getnstimeofday with getnstimeofday64. Also use parameters to convert the timespec64 values instead of hard code.

[PATCH 00/37] staging/lustre: y2038 rework

by Arnd Bergmann

First of all, sorry for the overly long series that this turned into. I'm currently doing a survey of all code using time_t/timeval/timespec to get an idea of what work needs to be done where, in particular in terms of user interface changes. Lustre is by far the most pervasive user of time types and functions, and I could not even find my way through the code to see what needs to be done other than actually doing that work. On most other subsystems, we try to use montonic times where possible for in-kernel uses. I did not do that here but kept using wall-clock times, in order to leave the debug output and procfs files untouched. A follow-up series could convert a lot of the ktime_get_real_*() to ktime_get_*() to change that if we don't care about the format. There are a couple of things that I left unchanged: - Socket timestamps in drivers/staging/lustre/lnet/lnet/lib-socket.c need to wait for the socket API to be changed first - inode timestamps need to be changed in VFS, which is a larger work - The conrpc selftest has a user interface based on timeval that is hard to change. All patches are based on staging-testing and built-tested on 32-bit arm and x86 as well as 64-bit arm. Arnd Bergmann (37): staging/lustre: use jiffies for lp_last_query times staging/lustre: use 64-bit inode timestamps internally staging/lustre: obd: remove unused data structures staging/lustre: tracefile: use 64-bit seconds staging/lustre: use 64-bit timestamps in procfs output staging/lustre: use time64_t for l_last_activity staging/lustre: use ktime_t for calculating elapsed time staging/lustre: change rq_at_index type staging/lustre: avoid unnecessary timeval conversion staging/lustre: use 64-bit time LNetCtl() staging/lustre: use 'long' return type for cfs_duration_sec() staging/lustre: use jiffies_to_timeval() instead of cfs_duration_usec staging/lustre: use 64-bit ibn_incarnation computation staging/lustre: use 64-bit times for lnet_shuffle_seed staging/lustre: use 64-bit computation in s2dhms() staging/lustre: use 64-bit timestamps for selftest staging/lustre: use 64-bit time for pl_recalc staging/lustre: use 64-bit time for obd eviction staging/lustre: use 64-bit time for procfs output staging/lustre: use 64-bit time for adaptive timeout staging/lustre: use 64-bit llite procfs timestamps staging/lustre: use 64-bit times for ksnd_connd staging/lustre: use 64-bit time for ni_last_alive staging/lustre: use 64-bit time for selftest staging/lustre: partially use time64_t for capa expiry staging/lustre: use 64-bit times in ptlrpc_enc_page_pool staging/lustre: use 64-bit times in debug print staging/lustre: use 64-bit times in another debug print staging/lustre: use 64-bit timestamps for mdc staging/lustre: use 64-bit times for ptlrpc sec expiry staging/lustre: use 64-bit times for ptlrpc_sec staging/lustre: use 64-bit times for exp_last_request_time staging/lustre: use 64-bit times for request times staging/lustre: remove a bit of dead code staging/lustre: remove wrappers for timer functions staging/lustre: remove unused time handling functions staging/lustre: remove CFS_TIME_T definition .../lustre/include/linux/libcfs/libcfs_debug.h | 4 +- .../lustre/include/linux/libcfs/libcfs_prim.h | 13 -- .../lustre/include/linux/libcfs/libcfs_time.h | 49 -------- .../lustre/include/linux/libcfs/linux/linux-time.h | 35 +----- .../staging/lustre/include/linux/lnet/lib-lnet.h | 2 +- .../staging/lustre/include/linux/lnet/lib-types.h | 2 +- .../staging/lustre/lnet/klnds/o2iblnd/o2iblnd.c | 6 +- .../staging/lustre/lnet/klnds/socklnd/socklnd.c | 2 +- .../staging/lustre/lnet/klnds/socklnd/socklnd.h | 6 +- .../staging/lustre/lnet/klnds/socklnd/socklnd_cb.c | 8 +- drivers/staging/lustre/lnet/lnet/api-ni.c | 6 +- drivers/staging/lustre/lnet/lnet/config.c | 2 +- drivers/staging/lustre/lnet/lnet/lib-eq.c | 9 +- drivers/staging/lustre/lnet/lnet/lib-move.c | 4 +- drivers/staging/lustre/lnet/lnet/router.c | 10 +- drivers/staging/lustre/lnet/lnet/router_proc.c | 2 +- drivers/staging/lustre/lnet/selftest/conctl.c | 2 +- drivers/staging/lustre/lnet/selftest/conrpc.c | 10 +- drivers/staging/lustre/lnet/selftest/console.c | 2 +- drivers/staging/lustre/lnet/selftest/console.h | 2 +- drivers/staging/lustre/lnet/selftest/framework.c | 5 +- drivers/staging/lustre/lnet/selftest/ping_test.c | 12 +- drivers/staging/lustre/lnet/selftest/rpc.c | 9 +- drivers/staging/lustre/lnet/selftest/selftest.h | 2 +- drivers/staging/lustre/lnet/selftest/timer.c | 14 +-- drivers/staging/lustre/lnet/selftest/timer.h | 2 +- drivers/staging/lustre/lustre/include/cl_object.h | 6 +- .../staging/lustre/lustre/include/lprocfs_status.h | 6 +- .../lustre/lustre/include/lustre/lustre_idl.h | 1 + .../staging/lustre/lustre/include/lustre_capa.h | 16 ++- drivers/staging/lustre/lustre/include/lustre_dlm.h | 6 +- .../staging/lustre/lustre/include/lustre_export.h | 7 +- .../staging/lustre/lustre/include/lustre_import.h | 14 +-- drivers/staging/lustre/lustre/include/lustre_net.h | 24 ++-- drivers/staging/lustre/lustre/include/lustre_sec.h | 2 +- drivers/staging/lustre/lustre/include/obd.h | 97 +-------------- drivers/staging/lustre/lustre/include/obd_class.h | 2 +- drivers/staging/lustre/lustre/ldlm/ldlm_lock.c | 2 +- drivers/staging/lustre/lustre/ldlm/ldlm_pool.c | 30 ++--- drivers/staging/lustre/lustre/ldlm/ldlm_request.c | 29 ++--- drivers/staging/lustre/lustre/libcfs/debug.c | 4 +- .../lustre/lustre/libcfs/linux/linux-prim.c | 70 ----------- .../lustre/lustre/libcfs/linux/linux-tracefile.c | 8 +- drivers/staging/lustre/lustre/libcfs/module.c | 3 -

[PATCH] dummy_hcd: replace timeval with timespec64

by WEN Pingbo

- what is the time_t/timeval/timespec type used for in this driver the timeval in dummy_g_get_frame is used for getting frame number in every ms. - is this broken in 2038 or not No. The millisecond of the last second will be normal if tv_sec is overflowed. But for consistency purpose, and avoiding further risks, I have replaced timeval with timespec64. - does the driver use monotonic or real time Real time. But only microsecond part is used. - if it uses real time, should it use monotonic time instead Monotonic time will be ok if it can meet the precise requirement(us).

[PATCH v3] net: rxrpc: Replace time_t with time64_t

by Ksenija Stanojevic

Replace all instances of time_t with time64_t i.e. change the type used for representing time from 32-bit to 64-bit. All 32-bit kernels to date use a signed 32-bit time_t type, which can only represent time until January 2038. The patch also changes the function get_seconds() that returns a 32-bit integer to ktime_get_seconds() that returns seconds as 64-bit integer and it uses monotonic instead of real time clock. Field expiry is changed to u64 in struct rxrpc_key_data_v1 and struct rxkad_key and to time64_t in key_preparsed_payload. This change is safe since field expiry is used only in this driver. Add macro ENCODE32 to export 64bit time to userspace as a 32bit data. Signed-off-by: Ksenija Stanojevic <ksenija.stanojevic(a)gmail.com> --- Changes in v3: - use ENCODE32 instead of ENCODE64 macro Changes in v2: - change the type of field expiry. - modify the assignement of field put_time. - modify the assignement of variable issue. include/keys/rxrpc-type.h | 4 ++-- include/linux/key-type.h | 2 +- net/rxrpc/ar-connection.c | 4 ++-- net/rxrpc/ar-internal.h | 6 +++--- net/rxrpc/ar-key.c | 16 +++++++++++----- net/rxrpc/ar-transport.c | 4 ++-- net/rxrpc/rxkad.c | 15 ++++++++------- 7 files changed, 29 insertions(+), 22 deletions(-) diff --git a/include/keys/rxrpc-type.h b/include/keys/rxrpc-type.h index fc48754..f13b2cb 100644 --- a/include/keys/rxrpc-type.h +++ b/include/keys/rxrpc-type.h @@ -27,7 +27,7 @@ extern struct key *rxrpc_get_null_key(const char *);

[PATCH] bnx2x: use ktime_get_seconds() for timestamp

by Arnd Bergmann

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

[PATCH v2 0/5] Introduce 64bit accessors and structures required to address y2038 issues in the posix_clock subsystem

by Baolin Wang

This patch series change the 32-bit time types (timespec/itimerspec) to the 64-bit types (timespec64/itimerspec64), and add new 64bit accessor functions, which are required in order to avoid y2038 issues in the posix_clock subsystem. In order to avoid spamming people too much, I'm only sending the first few patches of the patch series, and left the other patches for later. And if you are interested in the whole patch series, see: https://git.linaro.org/people/baolin.wang/upstream_0627.git Thoughts and feedback would be appreciated. Changes since v1: - Modify the changelog. - Delete one patch without y2038 safe.

[RFD PATCH 0/2] Convert sound subsystem to year 2038 safe

by Bamvor Zhang Jian

This is my first attempt to convert sound subsystem to year 2038 safe. In these series patches I focus on the timer. When check the time relative code in timer of sound subsystem, I feel that I could easy split 64bit time_xxx type in kernel and in userspace (__kernel_time_xxx) according to arnd's approach[1] in comparison with other parts of sound subsys(e.g. pcm). Whether I should follow the same approach in the whole sound subsystem is an open issue for me. On the other hand, there are difference approaches for dealing with the code in userspace. It seems that snd_timer_read is the only api for other parts of alsa. It share the same code no matter tread is true or false. The fisrt approach is hide __kernel_time_xxx inside snd_timer_read, although the code may be a little bit ugly. The second approach is that force userspace migration to 64bit time on all 32bit(including compat) system by re-definition the following types in alsa-lib/include/global.h: typedef struct __kernel_timespec snd_htimestamp_t; This approach will not affect the 64bit application.

I'm unsure if that would actually help anybody: The new version would only be seen for applications that are built with a 64-bit time_t, and that requires a new kernel for a number of reasons. It might help bridge the window between kernels that have support for basic syscalls but not a particular ioctl like this one, but approach so far was that I'd just treat that case as a bug and tell people to not expect 64-bit time_t in user space to work in all cases until we have a kernel that has all drivers converted.

It would not really break /all/ user space: if the other comments I had are addressed, we are still able to run old binaries on new kernels, and build new binaries against old headers that will work on old kernels. Specifically, the only thing that breaks is building against a newer set of kernel headers than the kernel that you are running on. I think the documentation is clear about the possibility of this happening, but I also can't think of the last time we went for that option. > > The alternative is to leave the 'timespec' visible here for user space, > > so user programs will see either the old or the new definition of struct > > depending on their timespec definition, and only programs built with > > 64-bit time_t will require new kernels. > > Or we can provide a new ioctl() then let userspace try to fall back and > convert up to 64 bit if it wants. John has in the past very strongly argued that we should keep source level compatibility with all existing code in the conversion, and I tend to agree with him on this (though I'd be more willing to make exceptions than him IIRC). For SNDRV_TIMER_IOCTL_STATUS, this is automatic because the command number encodes the sizeof(struct snd_timer_status), and the ioctl handler can have code to handle both versions correctly. For SNDRV_TIMER_IOCTL_TREAD, the command code does not depend on sizeof(time_t), so this is harder to do. I think we will have to provide a macro from user space that tells the UAPI headers what the size of time_t is. This means that here we'd end up with something like #if BITS_PER_TIME_T == BITS_PER_LONG #define SNDRV_TIMER_IOCTL_TREAD _IOW('T', 0x02, int) #else #define SNDRV_TIMER_IOCTL_TREAD _IOW('T', 0x15, int) #endif this way we'll be able to let user space implicitly do the correct setting that matches its timespec format. > > > +void snd_timer_notify(struct snd_timer *timer, int event, struct timespec *tstamp) > > > +{ > > > + struct timespec64 tstamp64; > > > + > > > + tstamp64.tv_sec = tstamp->tv_sec; > > > + tstamp64.tv_nsec = tstamp->tv_nsec; > > > + snd_timer_notify64(timer, event, &tstamp64); > > > +} > > > This works, but I'd leave it up to Mark if he'd prefer to do the conversion > > bit by bit and change over all users of snd_timer_notify to use > > snd_timer_notify64, or to move them all at once and leave the function > > name unchanged. > > That's more a question for Takashi than me, this is all generic > userspace stuff that is common to all sound.

[PATCH 0/6] Introduce 64bit accessors and structures required to address y2038 issues in the posix_clock subsystem

by Baolin Wang

This patch series change the 32-bit time types (timespec/itimerspec) to the 64-bit types (timespec64/itimerspec64), and add new 64bit accessor functions, which are required in order to avoid y2038 issues in the posix_clock subsystem. In order to avoid spamming people too much, I'm only sending the first few patches of the patch series, and left the other patches for later. And if you are interested in the whole patch series, see: https://git.linaro.org/people/baolin.wang/upstream_0627.git Thoughts and feedback would be appreciated. Baolin Wang (6): time: Introduce struct itimerspec64 timekeeping: Introduce current_kernel_time64() security: Introduce security_settime64() time: Introduce do_sys_settimeofday64() time: Introduce timespec64_to_jiffies()/jiffies_to_timespec64() cputime: Introduce cputime_to_timespec64()/timespec64_to_cputime() arch/powerpc/include/asm/cputime.h | 6 +++--- arch/s390/include/asm/cputime.h | 8 ++++---- include/asm-generic/cputime_jiffies.h | 10 +++++----- include/asm-generic/cputime_nsecs.h | 6 +++--- include/linux/cputime.h | 16 +++++++++++++++ include/linux/jiffies.h | 22 ++++++++++++++++++--- include/linux/lsm_hooks.h | 5 +++-- include/linux/security.h | 20 ++++++++++++++++--- include/linux/time64.h | 35 +++++++++++++++++++++++++++++++++ include/linux/timekeeping.h | 24 +++++++++++++++++++--- kernel/time/time.c | 28 +++++++++++++++----------- kernel/time/timekeeping.c | 6 +++--- security/commoncap.c | 2 +- security/security.c | 2 +- 14 files changed, 148 insertions(+), 42 deletions(-) -- 1.7.9.5

I add this ifdef because I got compile failure on arm platform. This file do not include the <linux/compat.h> directly. And in arm64, compat.h is included implicitily. So, I am not sure what I should do here. Include <linux/compat.h> in this file directly or add a this check at the beginning of this file? #ifndef is_compat_task #define is_compat_task() (0) #endif > Otherwise this looks similar to a patch Baolin (cc'ed) has been working on.

The main reason for using an __s64[2] array instead of struct __kernel_timeval is to avoid adding __kernel_timeval: 'timeval' is thoroughly deprecated and we don't want to establish new interfaces with that. In case of this driver, nobody would ever want to change their user space to use a 64-bit __kernel_timeval instead of timeval and explicitly call PPGETTIME64 instead of PPGETTIME, because we are only dealing with an interval here, and a 32-bit second value is sufficient to represent that. Instead, the purpose of your patch is to make the kernel cope with user space that happens to use a 64-bit time_t based definition of 'struct timeval' and passes that to the ioctl.

[PATCH v2] net: rxrpc: Replace time_t with time64_t

by Ksenija Stanojevic

Replace all instances of time_t with time64_t i.e. change the type used for representing time from 32-bit to 64-bit. All 32-bit kernels to date use a signed 32-bit time_t type, which can only represent time until January 2038. The patch also changes the function get_seconds() that returns a 32-bit integer to ktime_get_seconds() that returns seconds as 64-bit integer and it uses monotonic instead of real time clock. Field expiry is changed to u64 in struct rxrpc_key_data_v1 and struct rxkad_key and to time64_t in key_preparsed_payload. This change is safe since field expiry is used only in this driver. Signed-off-by: Ksenija Stanojevic <ksenija.stanojevic(a)gmail.com> --- Changes in v2: - change the type of field expiry. - modify the assignement of field put_time. - modify the assignement of variable issue. include/keys/rxrpc-type.h | 4 ++-- include/linux/key-type.h | 2 +- net/rxrpc/ar-connection.c | 4 ++-- net/rxrpc/ar-internal.h | 6 +++--- net/rxrpc/ar-key.c | 10 +++++----- net/rxrpc/ar-transport.c | 4 ++-- net/rxrpc/rxkad.c | 15 ++++++++------- 7 files changed, 23 insertions(+), 22 deletions(-) diff --git a/include/keys/rxrpc-type.h b/include/keys/rxrpc-type.h index fc48754..f13b2cb 100644 --- a/include/keys/rxrpc-type.h +++ b/include/keys/rxrpc-type.h @@ -27,7 +27,7 @@ extern struct key *rxrpc_get_null_key(const char *);
