[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59+00:00

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

[PATCH] sysctl: llc: remove unnecessary insert_at_head flag

2007-02-14T16:09:55+00:00

The sysctl numbers used are unique so setting the insert_at_head flag serves
no semantis purpose, and is just confusing.

[PATCH] mark struct file_operations const 8

2007-02-12T17:48:46+00:00

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

[LLC]: multicast receive device match

2006-08-14T01:56:26+00:00

Fix from Aji_Srinivas@emc.com, STP packets are incorrectly received on
all LLC datagram sockets, whichever interface they are bound to.  The
llc_sap datagram receive logic sends packets with a unicast
destination MAC to one socket bound to that SAP and MAC, and multicast
packets to all sockets bound to that SAP. STP packets are multicast,
and we do need to know on which interface they were received.

[LLX]: SOCK_DGRAM interface fixes

2006-08-05T05:59:50+00:00

The datagram interface of LLC is broken in a couple of ways.
These were discovered when trying to use it to build an out-of-kernel
version of STP.

First it didn't pass the source address of the received packet
in recvfrom(). It needs to copy the source address of received LLC packets
into the socket control block. At the same time fix a security issue
because there was uninitialized data leakage. Every recvfrom call
was just copying out old data.

Second, LLC should not merge multiple packets in one receive call
on datagram sockets. LLC should preserve packet boundaries on
SOCK_DGRAM.

This fix goes against the old historical comments about UNIX98 semantics
but without this fix SOCK_DGRAM is broken and useless. So either ANK's
interpretation was incorect or UNIX98 standard was wrong.
