Description Sergey Vlasov 2006-12-15 21:35:30 MSK
Between mount-2.12r-alt1 and mount-2.12r-alt3 handling of the "quiet" mount
option for vfat filesystem has been broken (/etc/mtab shows the "quiet" option,
but actually it is not enabled).

Steps to Reproduce:
With mount-2.12r-alt1:
# strace -q -e mount -s 1024 mount -t vfat -o quiet /dev/sdb1 /mnt/disk
mount("/dev/sdb1", "/mnt/disk", "vfat", MS_MGC_VAL, "quiet") = 0

With mount-2.12r-alt3:
# strace -q -e mount -s 1024 mount -t vfat -o quiet /dev/sdb1 /mnt/disk
mount("/dev/sdb1", "/mnt/disk", "vfat", MS_MGC_VAL|MS_VERBOSE, "") = 0
Comment 1 Dmitry V. Levin 2006-12-15 22:26:27 MSK
Between alt1 and alt2 (very likely) or between alt2 and alt3?
Comment 2 Sergey Vlasov 2006-12-15 22:33:45 MSK
Seems that the problem is caused by the addition of MS_SILENT to kernel headers:


Rebuilding mount-2.12r-alt1 package fails for me due to broken chstk on x86_64,
but the mount binary which gets built is broken in the same way (eats the
"quiet" option).
Comment 3 Dmitry V. Levin 2006-12-15 22:43:54 MSK
Yes, regression is due to rebuild.
Comment 4 Dmitry V. Levin 2006-12-16 00:03:10 MSK
Looks like MS_SILENT handling in mount is wrong:

#ifdef MS_SILENT
if (om->mask == MS_SILENT && om->inv)  {
        mount_quiet = 1;
        verbose = 0;

i.e. MS_SILENT meaning is reverted.
Comment 5 Dmitry V. Levin 2006-12-16 00:22:45 MSK
Cited hunk (while buggy) is not relevant to the problem.

I wonder how mount should work when "quiet" option is given.
Should it set MS_SILENT (== MS_VERBOSE) flag in mount(2) call?
Should it pass "quiet" option to mount(2) call?

Я бы хотел услышать предложения возможных решений.

Disabled MS_SILENT support in 2.12r-alt5.
