[PATCH RESEND] pipe: avoid creating empty pipe buffers

by Wiktor Garbacz

pipe_write cannot be called on notification pipes so post_one_notification cannot race it. Locking and second pipe_full check are thus redundant. This fixes an issue where pipe write could unexpectedly block: // Assume there is no reader or reader polls and uses FIONREAD ioctl // to read all the available bytes. for (int i = 0; i < PIPE_DEF_BUFFERS+1; ++i) { write(pipe_fd, buf_that_efaults, PAGE_SIZE); } // Never reached Fixes: a194dfe6e6f6 ("pipe: Rearrange sequence in pipe_write() to preallocate slot") Cc: stable(a)vger.kernel.org Signed-off-by: Wiktor Garbacz <wiktorg(a)google.com> --- fs/pipe.c | 35 +++++++++-------------------------- 1 file changed, 9 insertions(+), 26 deletions(-) diff --git a/fs/pipe.c b/fs/pipe.c index 42c7ff41c2db..87356a2823cf 100644 --- a/fs/pipe.c +++ b/fs/pipe.c @@ -501,43 +501,26 @@ pipe_write(struct kiocb *iocb, struct iov_iter *from) pipe->tmp_page = page; } - /* Allocate a slot in the ring in advance and attach an - * empty buffer.

[tip: x86/urgent] x86/debug: Fix stack recursion caused by wrongly ordered DR7 accesses

by tip-bot2 for Joerg Roedel

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 9d2c7203ffdb846399b82b0660563c89e918c751 Gitweb: https://git.kernel.org/tip/9d2c7203ffdb846399b82b0660563c89e918c751 Author: Joerg Roedel <jroedel(a)suse.de> AuthorDate: Tue, 31 Jan 2023 09:57:18 +01:00 Committer: Borislav Petkov (AMD) <bp(a)alien8.de> CommitterDate: Tue, 31 Jan 2023 12:51:19 +01:00 x86/debug: Fix stack recursion caused by wrongly ordered DR7 accesses In kernels compiled with CONFIG_PARAVIRT=n, the compiler re-orders the DR7 read in exc_nmi() to happen before the call to sev_es_ist_enter(). This is problematic when running as an SEV-ES guest because in this environment the DR7 read might cause a #VC exception, and taking #VC exceptions is not safe in exc_nmi() before sev_es_ist_enter() has run. The result is stack recursion if the NMI was caused on the #VC IST stack, because a subsequent #VC exception in the NMI handler will overwrite the stack frame of the interrupted #VC handler. As there are no compiler barriers affecting the ordering of DR7 reads/writes, make the accesses to this register volatile, forbidding the compiler to re-order them. [ bp: Massage text, make them volatile too, to make sure some aggressive compiler optimization pass doesn't discard them. ] Fixes: 315562c9af3d ("x86/sev-es: Adjust #VC IST Stack on entering NMI handler") Reported-by: Alexey Kardashevskiy <aik(a)amd.com> Signed-off-by: Joerg Roedel <jroedel(a)suse.de> Signed-off-by: Borislav Petkov (AMD) <bp(a)alien8.de> Cc: stable(a)vger.kernel.org Link: https://lore.kernel.org/r/20230127035616.508966-1-aik@amd.com --- arch/x86/include/asm/debugreg.h | 26 ++++++++++++++++++++++++-- 1 file changed, 24 insertions(+), 2 deletions(-) diff --git a/arch/x86/include/asm/debugreg.h b/arch/x86/include/asm/debugreg.h index b049d95..ca97442 100644 --- a/arch/x86/include/asm/debugreg.h +++ b/arch/x86/include/asm/debugreg.h @@ -39,7 +39,20 @@ static __always_inline unsigned long native_get_debugreg(int regno) asm("mov %%db6, %0" :"=r" (val)); break; case 7: - asm("mov %%db7, %0" :"=r" (val)); + /* + * Apply __FORCE_ORDER to DR7 reads to forbid re-ordering them + * with other code. + * + * This is needed because a DR7 access can cause a #VC exception + * when running under SEV-ES.

[tip: x86/urgent] x86/debug: Fix stack recursion caused by wrongly ordered DR7 accesses

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 31859551393bc00f705cae2e1f9d31b80c62f365 Gitweb: https://git.kernel.org/tip/31859551393bc00f705cae2e1f9d31b80c62f365 Author: Joerg Roedel <jroedel(a)suse.de> AuthorDate: Tue, 31 Jan 2023 09:57:18 +01:00 Committer: Borislav Petkov (AMD) <bp(a)alien8.de> CommitterDate: Tue, 31 Jan 2023 11:26:15 +01:00 x86/debug: Fix stack recursion caused by wrongly ordered DR7 accesses In kernels compiled with CONFIG_PARAVIRT=n, the compiler re-orders the DR7 read in exc_nmi() to happen before the call to sev_es_ist_enter(). This is problematic when running as an SEV-ES guest because in this environment the DR7 read might cause a #VC exception, and taking #VC exceptions is not safe in exc_nmi() before sev_es_ist_enter() has run. The result is stack recursion if the NMI was caused on the #VC IST stack, because a subsequent #VC exception in the NMI handler will overwrite the stack frame of the interrupted #VC handler. As there are no compiler barriers affecting the ordering of DR7 reads/writes, make the accesses to this register volatile, forbidding the compiler to re-order them. [ bp: Massage text, make them volatile too, to make sure some aggressive compiler optimization pass doesn't discard them. ] Fixes: 315562c9af3d ("x86/sev-es: Adjust #VC IST Stack on entering NMI handler") Reported-by: Alexey Kardashevskiy <aik(a)amd.com> Signed-off-by: Joerg Roedel <jroedel(a)suse.de> Signed-off-by: Borislav Petkov (AMD) <bp(a)alien8.de> Cc: stable(a)vger.kernel.org Link: https://lore.kernel.org/r/20230127035616.508966-1-aik@amd.com --- arch/x86/include/asm/debugreg.h | 27 ++++++++++++++++++++++++--- 1 file changed, 24 insertions(+), 3 deletions(-) diff --git a/arch/x86/include/asm/debugreg.h b/arch/x86/include/asm/debugreg.h index b049d95..ff1a924 100644 --- a/arch/x86/include/asm/debugreg.h +++ b/arch/x86/include/asm/debugreg.h @@ -39,7 +39,20 @@ static __always_inline unsigned long native_get_debugreg(int regno) asm("mov %%db6, %0" :"=r" (val)); break; case 7: - asm("mov %%db7, %0" :"=r" (val)); + /* + * Apply __FORCE_ORDER to DR7 reads to forbid re-ordering them + * with other code. + * + * This is needed because a DR7 access can cause a #VC exception + * when running under SEV-ES.

patch "iio: imu: fxos8700: fix MAGN sensor scale and unit" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: imu: fxos8700: fix MAGN sensor scale and unit to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know.

Magnetometer scale is the magnetic sensitivity parameter. It is referenced as 0.1uT according to datasheet and magnetometer channel unit is Gauss in sysfs-bus-iio documentation.

patch "iio: imu: fxos8700: fix failed initialization ODR mode assignment" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: imu: fxos8700: fix failed initialization ODR mode assignment to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know.

Select MAX ODR mode as the initialization ODR mode by field mask and FIELD_PREP.
