Sunrpc: Supports hexadecimal number for sysctl files of sunrpc debug

2015-11-03T20:56:49+00:00

The sunrpc debug sysctl files only accept decimal number right now.
But all the XXXDBUG_XXX macros are defined as hexadecimal.
It is not easy to set or check an separate flag.

This patch let those files support accepting hexadecimal number,
(decimal number is also supported). Also, display it as hexadecimal.

v2,
Remove duplicate parsing of '0x...', just using simple_strtol(tmpbuf, &s, 0)
Fix a bug of isspace() checking after parsing

2014-11-24T22:31:46+00:00

It's always set to whatever CONFIG_SUNRPC_DEBUG is, so just use that.

net: Convert uses of typedef ctl_table to struct ctl_table

2013-06-13T09:36:09+00:00

Reduce the uses of this unnecessary typedef.

Done via perl script:

$ git grep --name-only -w ctl_table net | \
  xargs perl -p -i -e '\
	sub trim { my ($local) = @_; $local =~ s/(^\s+|\s+$)//g; return $local; } \
        s/\b(?

SUNRPC: make SUNPRC clients list per network namespace context

2012-01-31T23:20:25+00:00

This patch moves static SUNRPC clients list and it's lock to sunrpc_net
structure.
Currently this list is used only for debug purposes. But later it will be used
also for selecting clients by networks namespace on PipeFS mount/umount events.
Per-network namespace lists will make this faster and simplier.

Note: client list is taken from "init_net" network namespace context in
rpc_show_tasks(). This will be changed some day later with making SUNRPC
sysctl's per network namespace context.

sysctl: Drop & in front of every proc_handler.

2009-11-18T16:37:40+00:00

For consistency drop & in front of every proc_handler.  Explicity
taking the address is unnecessary and it prevents optimizations
like stubbing the proc_handlers to NULL.

sysctl net: Remove unused binary sysctl code

2009-11-12T10:05:06+00:00

Now that sys_sysctl is a compatiblity wrapper around /proc/sys
all sysctl strategy routines, and all ctl_name and strategy
entries in the sysctl tables are unused, and can be
revmoed.

In addition neigh_sysctl_register has been modified to no longer
take a strategy argument and it's callers have been modified not
to pass one.

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

2009-09-24T14:21:04+00:00

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.

sunrpc: fix possible overrun on read of /proc/sys/sunrpc/transports

David Wagner added (among other things) that copy_to_user could be
probably used here.

Ingo Oeser suggested to use simple_read_from_buffer() here.

The conclusion is that proc_do_xprt doesn't check for userside buffer
size indeed so fix this by using Ingo's suggestion.

SUNRPC: Restrict sunrpc client exports

2008-01-30T07:05:28+00:00

The sunrpc client exports are not meant to be part of any official kernel
API: they can change at the drop of a hat. Mark them as internal functions
using EXPORT_SYMBOL_GPL.
