sys: don't hold uts_sem while accessing userspace memory

2018-09-09T17:56:00Z

commit 42a0cc3478584d4d63f68f2f5af021ddbea771fa upstream. Holding uts_sem as a writer while accessing userspace memory allows a namespace admin to stall all processes that attempt to take uts_sem. Instead, move data through stack buffers and don't access userspace memory while uts_sem is held.

sched/headers: Remove from

2017-03-03T00:45:36Z

This is a stray header that is not needed by anything in sched.h, so remove it. Update files that relied on the stray inclusion. This reduces the size of the header dependency graph. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Signed-off-by: Ingo Molnar

sysctl: convert use of typedef ctl_table to struct ctl_table

2014-06-06T23:08:16Z

This typedef is unnecessary and should just be removed. Signed-off-by: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kernel/utsname_sysctl.c: replace obsolete __initcall by device_initcall

kernel/utsname_sysctl.c: put get/get_uts() into CONFIG_PROC_SYSCTL code block

2013-02-28T03:10:22Z

Put get/get_uts() into CONFIG_PROC_SYSCTL code block as they are used only when CONFIG_PROC_SYSCTL is enabled. Signed-off-by: Yuanhan Liu Cc: "Eric W. Biederman" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sysctl: add support for poll()

2011-11-02T23:07:02Z

Adding support for poll() in sysctl fs allows userspace to receive notifications of changes in sysctl entries. This adds a infrastructure to allow files in sysctl fs to be pollable and implements it for hostname and domainname.

kernel: Map most files to use export.h instead of module.h

2011-10-31T13:20:12Z

The changed files were only including linux/module.h for the EXPORT_SYMBOL infrastructure, and nothing else. Revector them onto the isolated export header for faster compile times. Nothing to see here but a whole lot of instances of: -#include +#include This commit is only changing the kernel dir; next targets will probably be mm, fs, the arch dirs, etc. Signed-off-by: Paul Gortmaker

sysctl kernel: Remove binary sysctl logic

2009-11-12T10:04:55Z

Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name and .strategy members of sysctl tables are dead code. Remove them. Cc: Ingo Molnar Cc: Peter Zijlstra Cc: David Howells Signed-off-by: Eric W. Biederman

sysctl: remove "struct file *" argument of ->proc_handler

2009-09-24T14:21:04Z

It's unused. It isn't needed -- read or write flag is already passed and sysctl shouldn't care about the rest. It _was_ used in two places at arch/frv for some reason.
