On the server, this is processed # by truncating the file to new size and then writing the data. # # Now, kafs has a lock (vnode->io_lock) that serves to serialise # operations against a specific vnode (ie. inode), but the parameters for # the op are set before the lock is taken. This allows two writebacks # (say sync and kswapd) to race - and if writes are ongoing the writeback # for a later write could occur before the writeback for an earlier one if # the latter gets interrupted. # # Note that afs_writepages() cannot take i_mutex and only takes a shared # lock on vnode->validate_lock. # # Also note that the server does the truncation and the write inside a # lock, so there's no problem at that end. # # Fix this by moving the calculation for the proposed new i_size inside # the vnode->io_lock. Also reset the iterator (which we might have read # from) and update the mtime setting there. # # Fixes: bd80d8a80e12 ("afs: Use ITER_XARRAY for writing") # Reported-by: Marc Dionne <marc.dionne@auristor.com> # Signed-off-by: David Howells <dhowells@redhat.com> # Reviewed-by: Jeffrey Altman <jaltman@auristor.com> # Reviewed-by: Marc Dionne <marc.dionne@auristor.com> # cc: linux-afs@lists.infradead.org # cc: linux-fsdevel@vger.kernel.org # Link: https://lore.kernel.org/r/3526895.1687960024@warthog.procyon.org.uk/ # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 03275585cabd0240944f19f33d7584a1b099a3a8 # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- se7619_defconfig # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/drivers/char/mem.c: In function 'read_mem': /kisskb/src/drivers/char/mem.c:164:25: error: implicit declaration of function 'unxlate_dev_mem_ptr'; did you mean 'xlate_dev_mem_ptr'?
