[ Upstream commit 1f935e8e72ec28dddb2dc0650b3b6626a293d94b ]
For AF_VSOCK, accept() currently returns sockets that are unlabelled. Other socket families derive the child's SID from the SID of the parent and the SID of the incoming packet. This is typically done as the connected socket is placed in the queue that accept() removes from.
Reuse the existing 'security_sk_clone' hook to copy the SID from the parent (server) socket to the child. There is no packet SID in this case.

[ Upstream commit dcc32f4f183ab8479041b23a1525d48233df1d43 ]
This reverts commit 6af1799aaf3f1bc8defedddfa00df3192445bbf3.
Commit 6af1799aaf3f ("ipv6: drop incoming packets having a v4mapped source address") introduced an input check against v4mapped addresses. Use of such addresses on the wire is indeed questionable and not allowed on public Internet. As the commit pointed out
https://tools.ietf.org/html/draft-itojun-v6ops-v4mapped-harmful-02
lists potential issues.
Unfortunately there are applications which use v4mapped addresses, and breaking them is a clear regression. For example v4mapped addresses (or any semi-valid addresses, really) may be used for uni-direction event streams or packet export.
Since the issue which sparked the addition of the check was with TCP and request_socks in particular push the check down to TCPv6 and DCCP. This restores the ability to receive UDPv6 packets with v4mapped address as the source.
Keep using the IPSTATS_MIB_INHDRERRORS statistic to minimize the user-visible changes.

[ Upstream commit 0ddc942394013f08992fc379ca04cffacbbe3dae ]
I think this is unlikely but possible:
svc_authenticate sets rq_authop and calls svcauth_gss_accept. The kmalloc(sizeof(*svcdata), GFP_KERNEL) fails, leaving rq_auth_data NULL, and returning SVC_DENIED.
This causes svc_process_common to go to err_bad_auth, and eventually call svc_authorise. That calls ->release == svcauth_gss_release, which tries to dereference rq_auth_data.

[ Upstream commit cfa26ed1f9f885c2fd8f53ca492989d1e16d0199 ]
The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale.
E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer.
Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize.
Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

[ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ]
According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions:
| BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC |
The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet.
The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors.
Also, all credit for this patch should go to my colleague Dan MacDonald dmacdonald@curbellmedical.com for finding this error in the first place.

In ext4_rename(), when RENAME_WHITEOUT failed to add new entry into directory, it ends up dropping new created whiteout inode under the running transaction. After commit <9b88f9fb0d2> ("ext4: Do not iput inode under running transaction"), we follow the assumptions that evict() does not get called from a transaction context but in ext4_rename() it breaks this suggestion. Although it's not a real problem, better to obey it, so this patch add inode to orphan list and stop transaction before final iput().

[ Upstream commit 39935dccb21c60f9bbf1bb72d22ab6fd14ae7705 ]
If a DDP broadcast packet is sent out to a non-gateway target, it is also looped back. There is a potential for the loopback device to have a longer hardware header length than the original target route's device, which can result in the skb not being created with enough room for the loopback device's hardware header. This patch fixes the issue by determining that a loopback will be necessary prior to allocating the skb, and if so, ensuring the skb has enough room.
This was discovered while testing a new driver that creates a LocalTalk network interface (LTALK_HLEN = 1). It caused an skb_under_panic.

commit e54f30befa7990b897189b44a56c1138c6bfdbb5 upstream.
We found the alc_update_headset_mode() is not called on some machines when unplugging the headset, as a result, the mode of the ALC_HEADSET_MODE_UNPLUGGED can't be set, then the current_headset_type is not cleared, if users plug a differnt type of headset next time, the determine_headset_type() will not be called and the audio jack is set to the headset type of previous time.
On the Dell machines which connect the dmic to the PCH, if we open the gnome-sound-setting and unplug the headset, this issue will happen. Those machines disable the auto-mute by ucm and has no internal mic in the input source, so the update_headset_mode() will not be called by cap_sync_hook or automute_hook when unplugging, and because the gnome-sound-setting is opened, the codec will not enter the runtime_suspend state, so the update_headset_mode() will not be called by alc_resume when unplugging. In this case the hp_automute_hook is called when unplugging, so add update_headset_mode() calling to this function.

commit 9deb193af69d3fd6dd8e47f292b67c805a787010 upstream.
Commit cbc3b92ce037 fixed an issue to modify the macros of the stack trace event so that user space could parse it properly. Originally the stack trace format to user space showed that the called stack was a dynamic array. But it is not actually a dynamic array, in the way that other dynamic event arrays worked, and this broke user space parsing for it. The update was to make the array look to have 8 entries in it. Helper functions were added to make it parse it correctly, as the stack was dynamic, but was determined by the size of the event stored.
Although this fixed user space on how it read the event, it changed the internal structure used for the stack trace event. It changed the array size from [0] to [8] (added 8 entries). This increased the size of the stack trace event by 8 words. The size reserved on the ring buffer was the size of the stack trace event plus the number of stack entries found in the stack trace. That commit caused the amount to be 8 more than what was needed because it did not expect the caller field to have any size. This produced 8 entries of garbage (and reading random data) from the stack trace event:
<idle>-0 [002] d... 1976396.837549: <stack trace> => trace_event_raw_event_sched_switch => __traceiter_sched_switch => __schedule => schedule_idle => do_idle => cpu_startup_entry => secondary_startup_64_no_verify => 0xc8c5e150ffff93de => 0xffff93de => 0 => 0 => 0xc8c5e17800000000 => 0x1f30affff93de => 0x00000004 => 0x200000000
Instead, subtract the size of the caller field from the size of the event to make sure that only the amount needed to store the stack trace is reserved.

There are code paths that rely on zero_pfn to be fully initialized before core_initcall. For example, wq_sysfs_init() is a core_initcall function that eventually results in a call to kernel_execve, which causes a page fault with a subsequent mmput. If zero_pfn is not initialized by then it may not get cleaned up properly and result in an error:
BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1
Here is an analysis of the race as seen on a MIPS device. On this particular MT7621 device (Ubiquiti ER-X), zero_pfn is PFN 0 until initialized, at which point it becomes PFN 5120:
1. wq_sysfs_init calls into kobject_uevent_env at core_initcall: kobject_uevent_env+0x7e4/0x7ec kset_register+0x68/0x88 bus_register+0xdc/0x34c subsys_virtual_register+0x34/0x78 wq_sysfs_init+0x1c/0x4c do_one_initcall+0x50/0x1a8 kernel_init_freeable+0x230/0x2c8 kernel_init+0x10/0x100 ret_from_kernel_thread+0x14/0x1c
2. kobject_uevent_env() calls call_usermodehelper_exec() which executes kernel_execve asynchronously.
3. Memory allocations in kernel_execve cause a page fault, bumping the MM reference counter: add_mm_counter_fast+0xb4/0xc0 handle_mm_fault+0x6e4/0xea0 __get_user_pages.part.78+0x190/0x37c __get_user_pages_remote+0x128/0x360 get_arg_page+0x34/0xa0 copy_string_kernel+0x194/0x2a4 kernel_execve+0x11c/0x298 call_usermodehelper_exec_async+0x114/0x194
4. In case zero_pfn has not been initialized yet, zap_pte_range does not decrement the MM_ANONPAGES RSS counter and the BUG message is triggered shortly afterwards when __mmdrop checks the ref counters: __mmdrop+0x98/0x1d0 free_bprm+0x44/0x118 kernel_execve+0x160/0x1d8 call_usermodehelper_exec_async+0x114/0x194 ret_from_kernel_thread+0x14/0x1c
To avoid races such as described above, initialize init_zero_pfn at early_initcall level. Depending on the architecture, ZERO_PAGE is either constant or gets initialized even earlier, at paging_init, so there is no issue with initializing zero_pfn earlier.

commit 5e46d1b78a03d52306f21f77a4e4a144b6d31486 upstream.
syzbot is reporting NULL pointer dereference at reiserfs_security_init() [1], for commit ab17c4f02156c4f7 ("reiserfs: fixup xattr_root caching") is assuming that REISERFS_SB(s)->xattr_root != NULL in reiserfs_xattr_jcreate_nblocks() despite that commit made REISERFS_SB(sb)->priv_root != NULL && REISERFS_SB(s)->xattr_root == NULL case possible.
I guess that commit 6cb4aff0a77cc0e6 ("reiserfs: fix oops while creating privroot with selinux enabled") wanted to check xattr_root != NULL before reiserfs_xattr_jcreate_nblocks(), for the changelog is talking about the xattr root.
The issue is that while creating the privroot during mount reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which dereferences the xattr root. The xattr root doesn't exist, so we get an oops.
Therefore, update reiserfs_xattrs_initialized() to check both the privroot and the xattr root.

[ Upstream commit 829933ef05a951c8ff140e814656d73e74915faf ]
For each device, the nosy driver allocates a pcilynx structure. A use-after-free might happen in the following scenario:
1. Open nosy device for the first time and call ioctl with command NOSY_IOC_START, then a new client A will be malloced and added to doubly linked list. 2. Open nosy device for the second time and call ioctl with command NOSY_IOC_START, then a new client B will be malloced and added to doubly linked list. 3. Call ioctl with command NOSY_IOC_START for client A, then client A will be readded to the doubly linked list. Now the doubly linked list is messed up. 4. Close the first nosy device and nosy_release will be called. In nosy_release, client A will be unlinked and freed. 5. Close the second nosy device, and client A will be referenced, resulting in UAF.
The root cause of this bug is that the element in the doubly linked list is reentered into the list.
Fix this bug by adding a check before inserting a client. If a client is already in the linked list, don't insert it.
The following KASAN report reveals it:

commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd upstream.
This LTE modem (M.2 card) has a bug in its power management: there is some kind of race condition for U3 wake-up between the host and the device. The modem firmware sometimes crashes/locks when both events happen at the same time and the modem fully drops off the USB bus (and sometimes re-enumerates, sometimes just gets stuck until the next reboot).
Tested with the modem wired to the XHCI controller on an AMD 3015Ce platform. Without the patch, the modem dropped of the USB bus 5 times in 3 days. With the quirk, it stayed connected for a week while the 'runtime_suspended_time' counter incremented as excepted.

commit 72ad25fbbb78930f892b191637359ab5b94b3190 upstream.
The variable "info_element" is of the following type:
struct rtllib_info_element *info_element
defined in drivers/staging/rtl8192e/rtllib.h:
struct rtllib_info_element { u8 id; u8 len; u8 data[]; } __packed;
The "len" field defines the size of the "data[]" array. The code is supposed to check if "info_element->len" is greater than 4 and later equal to 6. If this is satisfied then, the last two bytes (the 4th and 5th element of u8 "data[]" array) are copied into "network->CcxRmState".
Right now the code uses "memcpy()" with the source as "&info_element[4]" which would copy in wrong and unintended information. The struct "rtllib_info_element" has a size of 2 bytes for "id" and "len", therefore indexing will be done in interval of 2 bytes. So, "info_element[4]" would point to data which is beyond the memory allocated for this pointer (that is, at x+8, while "info_element" has been allocated only from x to x+7 (2 + 6 => 8 bytes)).
This patch rectifies this error by using "&info_element->data[4]" which correctly copies the last two bytes of "data[]".
NOTE: The faulty line of code came from the following commit:
commit ecdfa44610fa ("Staging: add Realtek 8192 PCI wireless driver")
The above commit created the file `rtl8192e/ieee80211/ieee80211_rx.c` which had the faulty line of code. This file has been deleted (or possibly renamed) with the contents copied in to a new file `rtl8192e/rtllib_rx.c` along with additional code in the commit 94a799425eee (tagged in Fixes).

commit e78836ae76d20f38eed8c8c67f21db97529949da upstream.
The "u16 CcxRmState[2];" array field in struct "rtllib_network" has 4 bytes in total while the operations performed on this array through-out the code base are only 2 bytes.
The "CcxRmState" field is fed only 2 bytes of data using memcpy():
(In rtllib_rx.c:1972) memcpy(network->CcxRmState, &info_element->data[4], 2)
With "info_element->data[]" being a u8 array, if 2 bytes are written into "CcxRmState" (whose one element is u16 size), then the 2 u8 elements from "data[]" gets squashed and written into the first element ("CcxRmState[0]") while the second element ("CcxRmState[1]") is never fed with any data.
Same in file rtllib_rx.c:2522: memcpy(dst->CcxRmState, src->CcxRmState, 2);
The above line duplicates "src" data to "dst" but only writes 2 bytes (and not 4, which is the actual size). Again, only 1st element gets the value while the 2nd element remains uninitialized.
This later makes operations done with CcxRmState unpredictable in the following lines as the 1st element is having a squashed number while the 2nd element is having an uninitialized random number.
rtllib_rx.c:1973: if (network->CcxRmState[0] != 0) rtllib_rx.c:1977: network->MBssidMask = network->CcxRmState[1] & 0x07;
network->MBssidMask is also of type u8 and not u16.
Fix this by changing the type of "CcxRmState" from u16 to u8 so that the data written into this array and read from it make sense and are not random values.
NOTE: The wrong initialization of "CcxRmState" can be seen in the following commit:
commit ecdfa44610fa ("Staging: add Realtek 8192 PCI wireless driver")
