vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^$[^\"]*$$\$/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro Signed-off-by: Linus Torvalds

ipmi: create hardware-independent softdep for ipmi_devintf

2016-12-12T20:26:29+00:00

When a computer has an IPMI system interface, the device interface is most probably also desired. Autoloading of ipmi_devintf currently works only if ipmi_si has allocated a platform device. That doesn't happen if the SI interface was detected e.g. via ACPI. But ACPI detection is preferred these days, see e.g. kernel.org bug 46741. This patch introduces a softdep in place of the existing modalias for ipmi_devintf. Signed-off-by: Martin Wilck Suggested-by: Takashi Iwai I moved this to ipmi_msghandler.c, so it works for all IPMI interfaces. Retested by Martin.

ipmi: Free ipmi_recv_msg messages from the linked list on close

2015-02-20T02:58:40+00:00

This adds a loop through the elements in the linked list, recv_msgs using list_for_entry_safe in order to free messages in this list. In addition we are using the safe version of this marco in order to prevent use after bugs related to deleting the element we are on currently by holding a pointer to the next element after the current one we are on and freeing with the function, ipmi_free_recv_msg internally in this loop.

ipmi: ipmi_devintf: compat_ioctl method fails to take ipmi_mutex

2013-05-16T20:49:25+00:00

When a 32 bit version of ipmitool is used on a 64 bit kernel, the ipmi_devintf code fails to correctly acquire ipmi_mutex. This results in incomplete data being retrieved in some cases, or other possible failures. Add a wrapper around compat_ipmi_ioctl() to take ipmi_mutex to fix this.
