sysctl: Move the implementation into fs/proc/proc_sysctl.c

2012-01-25T00:37:54+00:00

Move the core sysctl code from kernel/sysctl.c and kernel/sysctl_check.c into fs/proc/proc_sysctl.c. Currently sysctl maintenance is hampered by the sysctl implementation being split across 3 files with artificial layering between them. Consolidate the entire sysctl implementation into 1 file so that it is easier to see what is going on and hopefully allowing for simpler maintenance. For functions that are now only used in fs/proc/proc_sysctl.c remove their declarations from sysctl.h and make them static in fs/proc/proc_sysctl.c Signed-off-by: Eric W. Biederman

xfs: remove subdirectories

2011-08-12T21:21:35+00:00

Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.

sysctl_check: drop table->procname checks

2011-03-24T02:46:50+00:00

sysctl: min/max bounds are optional

2010-10-15T21:42:24+00:00

sysctl check complains with a WARN() when proc_doulongvec_minmax() or proc_doulongvec_ms_jiffies_minmax() are used by a vector of longs (with more than one element), with no min or max value specified. This is unexpected, given we had a bug on this min/max handling :) Reported-by: Jiri Slaby Signed-off-by: Eric Dumazet Cc: "Eric W.

sysctl: Remove dead code from sysctl_check

2009-11-11T08:42:53+00:00

Now that the sys_sysctl is now a compatibility wrapper around /proc/sys we can remove much of sysctl_check and reduce it to a few remaining sanity checks. This completely decouples it from the binary sysctl system call. Little things like ensuring that the sysctl has not already been registered are all that remain. Signed-off-by: Eric W. Biederman

sysctl: fix false positives when PROC_SYSCTL=n

2009-10-29T14:39:30+00:00

Having ->procname but not ->proc_handler is valid when PROC_SYSCTL=n, people use such combination to reduce ifdefs with non-standard handlers.

net: add ARP notify option for devices

This adds another inet device option to enable gratuitous ARP when device is brought up or address change. This is handy for clusters or virtualization. Signed-off-by: Stephen Hemminger Signed-off-by: Jeremy Fitzhardinge Signed-off-by: David S. Miller

[XFS] remove restricted chown parameter from xfs linux

2008-10-30T07:30:09+00:00

On Linux all filesystems are supposed to be operating under Posix' restricted chown. Restricted chown means it restricts chown to the owner unless you have CAP_FOWNER. NOTE: that 2 files outside of fs/xfs have been modified too for this change.
