2007-02-12[PATCH] mark struct file_operations const 7Arjan van de Ven
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.

2006-12-17[AX.25]: Mark all kmalloc users __must_checkRalf Baechle
The recent fix 0506d4068bad834aab1141b5dc5e748eb175c6b3 made obvious that error values were not being propagated through the AX.25 stack. To help with that this patch marks all kmalloc users in the AX.25, NETROM and ROSE stacks as __must_check. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

2006-01-03[NET]: Add a dev_ioctl() fallback to sock_ioctl()Christoph Hellwig
Currently all network protocols need to call dev_ioctl as the default fallback in their ioctl implementations. This patch adds a fallback to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD. This way all the procotol ioctl handlers can be simplified and we don't need to export dev_ioctl.

2006-01-03[NET]: move struct proto_ops to constEric Dumazet
I noticed that some of 'struct proto_ops' used in the kernel may share a cache line used by locks or other heavily modified data. (default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2005-08-23[AX25]: UID fixesRalf Baechle
o Brown paperbag bug - ax25_findbyuid() was always returning a NULL pointer as the result. Breaks ROSE completly and AX.25 if UID policy set to deny. o While the list structure of AX.25's UID to callsign mapping table was properly protected by a spinlock, it's elements were not refcounted resulting in a race between removal and usage of an element.

2005-08-23[NET]: Fix socket bitop damageRalf Baechle
The socket flag cleanups that went into 2.6.12-rc1 are basically oring the flags of an old socket into the socket just being created. Unfortunately that one was just initialized by sock_init_data(), so already has SOCK_ZAPPED set. As the result zapped sockets are created and all incoming connection will fail due to this bug which again was carefully replicated to at least AX.25, NET/ROM or ROSE. In order to keep the abstraction alive I've introduced sock_copy_flags() to copy the socket flags from one sockets to another and used that instead of the bitwise copy thing. Anyway, the idea here has probably been to copy all flags, so sock_copy_flags() should be the right thing. With this the ham radio protocols are usable again, so I hope this will make it into 2.6.13.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
