All the bsdacct-related info will be stored in the area, pointer by this one. It will be NULL automatically for all new namespaces. Signed-off-by:

It makes many fields initialization implicit helping in auto-setting #ifdef-ed fields (bsd-acct related pointer will be such). Signed-off-by:

After I fixed access to task->tgid in kernel/acct.c, Oleg pointed out some bad side effects with this accounting vs pid namespaces interaction. I.e. when some task in pid namespace sets this accounting up, this blocks all the others from doing the same. Restricting this to init namespace only could help, but didn't look a graceful solution. So here is the approach to make this accounting work with pid namespaces properly. The idea is simple - when a task dies it accounts itself in each namespace it is visible from and which set the accounting up. For example here are the commands run and the output of lastcomm from init and sub namespaces: init_ns# accton pacct sub_ns# accton pacct (this is a different file - sub ns is run in a chroot-ed environment) init_ns# cat /dev/null sub_ns# ls /dev/null init_ns# accton sub_ns# accton sub_ns# lastcomm -f pacct ls 0 [136,0] 0.00 secs Thu May 15 10:30 accton 0 [136,0] 0.00 secs Thu May 15 10:30 init_ns# lastcomm -f pacct accton root pts/0 0.00 secs Thu May 15 14:30 << got from sub cat root pts/1 0.00 secs Thu May 15 14:30 ls root pts/0 0.00 secs Thu May 15 14:30 << got from sub accton root pts/1 0.00 secs Thu May 15 14:30 That was the summary, the details are in patches. This patch: It will be visible in pid_namespace.h file, so fix its name to look better outside the acct.c file. Signed-off-by: -

Adapt acct_update_integrals() to include user time when calculating the time difference. The units of acct_rss_mem1 and acct_vm_mem1 are also changed from pages-jiffies to pages-usecs to avoid calling jiffies_to_usecs() in xacct_add_tsk() which might overflow. Signed-off-by:

rcu_barrier_sched() and call_rcu_sched() were introduced in 2.6.26 for the Markers. Change the marker code to use them. It can be seen as a fix since the marker code was using an ugly, temporary, #ifdef hack to work around CONFIG_PREEMPT_RCU. Signed-off-by:

It seems to me that it was a mistake marking this function as deprecated and scheduling it for removal, rather than resolutely removing it after the last caller's death. Anyway - better late, then never. Signed-off-by:

This one had the only users so far - the kill_proc, which is removed, so drop this (invalid in namespaced world) call too. And of course - erase all references on it from comments. Signed-off-by:

This function operated on a pid_t to kill a task, which is no longer valid in a containerized system. It has finally lost all its users and we can safely remove it from the tree. Signed-off-by:

When struct pid is built on a 64 bit platform gcc has to insert padding to maintain the correct alignment, by simply reordering its members the memory usage shrinks from 88 bytes to 80. I've successfully run with this patch on my desktop AMD64 machine. There are no significant kernel size changes to a default config.X86_64 on the latest git v2.6.26-rc1 text data bss dec hex filename 5404828 976760 734280 7115868 6c945c vmlinux 5404811 976760 734280 7115851 6c944b vmlinux.pid-patch Acked-by:

Extend the permission check for networking sysctl's to allow modification when current process has CAP_NET_ADMIN capability and is not root. This version uses the until now unused permissions hook to override the mode value for /proc/sys/net if accessed by a user with capabilities. Found while working with Quagga. It is impossible to turn forwarding on/off through the command interface because Quagga uses secure coding practice of dropping privledges during initialization and only raising via capabilities when necessary. Since the dameon has reset real/effective uid after initialization, all attempts to access /proc/sys/net variables will fail. Signed-off-by:

Current two-stage scheme of removing PDE emphasizes one bug in proc: open rmmod remove_proc_entry close ->release won't be called because ->proc_fops were cleared. In simple cases it's small memory leak. For every ->open, ->release has to be done. List of openers is introduced which is traversed at remove_proc_entry() if neeeded. Discussions with Al long ago (sigh). Signed-off-by:
