* x86: randomize brkJiri Kosina2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Randomize the location of the heap (brk) for i386 and x86_64. The range is randomized in the range starting at current brk location up to 0x02000000 offset for both architectures. This, together with pie-executable-randomization.patch and pie-executable-randomization-fix.patch, should make the address space randomization on i386 and x86_64 complete. Arjan says: This is known to break older versions of some emacs variants, whose dumper code assumed that the last variable declared in the program is equal to the start of the dynamically allocated memory region. (The dumper is the code where emacs effectively dumps core at the end of it's compilation stage; this coredump is then loaded as the main program during normal use) iirc this was 5 years or so; we found this way back when I was at RH and we first did the security stuff there (including this brk randomization). It wasn't all variants of emacs, and it got fixed as a result (I vaguely remember that emacs already had code to deal with it for other archs/oses, just ifdeffed wrongly). It's a rare and wrong assumption as a general thing, just on x86 it mostly happened to be true (but to be honest, it'll break too if gcc does something fancy or if the linker does a non-standard order). Still its something we should at least document. Note 2: afaik it only broke the emacs *build*. I'm not 100% sure about that (it IS 5 years ago) though.

* NFS: Address memory leaks in the NFS client mount option parserChuck Lever2008-01-30
| | | | | | | | | | | | | | | David Howells noticed that repeating the same mount option twice during an NFS mount request can result in orphaned memory in certain cases. Only the client_address and mount_server.hostname strings are initialized in the mount parsing loop, so those appear to be the only two pointers that might be written over by repeating a mount option. The strings in the nfs_server section of the nfs_parsed_mount_data structure are set only once after the options are parsed, thus these are not susceptible to being overwritten.

* NFS: Optimise away the sigmask code in aio/dio reads and writesTrond Myklebust2008-01-30
| | | | | | | | | | | | There are no interruptible waits for asynchronous RPC tasks, so we don't need to wrap calls to rpc_run_task() with an rpc_clnt_sigmask/rpc_clnt_unsigmask pair. Instead we can wrap the wait_for_completion_interruptible() in nfs_direct_wait(). This means that we completely optimise away sigmask setting for the case of non-blocking aio/dio.

* NLM/NFS: Use cached nlm_host when calling nlmclnt_proc()Chuck Lever2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that each NFS mount point caches its own nlm_host structure, it can be passed to nlmclnt_proc() for each lock request. By pinning an nlm_host for each mount point, we trade the overhead of looking up or creating a fresh nlm_host struct during every NLM procedure call for a little extra memory. We also restrict the nlmclnt_proc symbol to limit the use of this call to in-tree modules. Note that nlm_lookup_host() (just removed from the client's per-request NLM processing) could also trigger an nlm_host garbage collection. Now client-side nlm_host garbage collection occurs only during NFS mount processing. Since the NFS client now holds a reference on these nlm_host structures, they wouldn't have been affected by garbage collection anyway. Given that nlm_lookup_host() reorders the global nlm_host chain after every successful lookup, and that a garbage collection could be triggered during the call, we've removed a significant amount of per-NLM-request CPU processing overhead. Sidebar: there are only a few remaining references to the internals of NFS inodes in the client-side NLM code. The only references I found are related to extracting or comparing the inode's file handle via NFS_FH(). One is in nlmclnt_grant(); the other is in nlmclnt_setlockargs().

* NFS: Invoke nlmclnt_init during NFS mount processingChuck Lever2008-01-30
| | | | | | | | | | | | Cache an appropriate nlm_host structure in the NFS client's mount point metadata for later use. Note that there is no need to set NFS_MOUNT_NONLM in the error case -- if nfs_start_lockd() returns a non-zero value, its callers ensure that the mount request fails outright.

* NLM: Introduce external nlm_host set-up and tear-down functionsChuck Lever2008-01-30
| | | | | | | | | | | | | | | | | We would like to remove the per-lock-operation nlm_lookup_host() call from nlmclnt_proc(). The new architecture pins an nlm_host structure to each NFS client superblock that has the "lock" mount option set. The NFS client passes in the pinned nlm_host structure during each call to nlmclnt_proc(). NFS client unmount processing "puts" the nlm_host so it can be garbage- collected later. This patch introduces externally callable NLM functions that handle mount-time nlm_host set up and tear-down.

Note this is mostly a cosmetic change, and does not actually allow referrals using IPv6 addresses. The existing referral code assumes that the server returns a string that represents an IPv4 address. This code needs to support hostnames and IPv6 addresses as well as IPv4 addresses, thus it will need to be reorganized completely (to handle DNS resolution in user space).
