2005-06-22[PATCH] isofs: show hidden files, add granularity for assoc/hidden files flagsJeremy White4-18/+36
The current isofs treatment of hidden files is flawed in two ways. First, it does not provide sufficient granularity; it hides both 'hidden' files and 'associated' files (resource fork for Mac files). Second, the default behavior to completely strip hidden files, while an admirable implementation of the spec, is a poor choice given the real world use of hidden files as a poor mans copy protection scheme for MSDOS and Windows based systems. A longer description of this is available here: http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html This patch was originally built after a few private conversations with Alan Cox; I shamefully failed to persist in seeing it go forward, I hope to make amends now. This patch introduces granularity by allowing explicit control for both hidden and associated files. It also reverses the default so that by default, hidden files are treated as regular files on the iso9660 file system. This allow Wine to process Windows CDs, including those that are hybrid Mac/Windows CDs properly and completely, without our having to go muck up peoples fstabs as we do now. (I have tested this with such a hybrid + hidden CD and have verified that this patch works as claimed).

2005-06-22[PATCH] rock.c: handle corrupted directoriesAndrew Morton1-0/+13
The bug in rock.c is that it's totally trusting of the contents of the directories. If the directory says there's a continuation 10000 bytes into this 4k block then we cheerily poke around in memory we don't own and oops. So change rock_continue() to apply various sanity checks, at least ensuring that the offset+length remain within the bounds for the header part of a struct rock_ridge directory entry. Note that the kernel can still overindex the buffer due to the variable size of the rock-ridge directory entries. We cannot check that in rock_continue() unless we go parse the directory entry's signature and work out its size.

2005-06-22[PATCH] autofs4: bad lookup fixIan Kent1-1/+8
For browsable autofs maps, a mount request that arrives at the same time an expire is happening can fail to perform the needed mount. This happens becuase the directory exists and so the revalidate succeeds when we need it to fail so that lookup is called on the same dentry to do the mount. Instead lookup is called on the next path component which should be whithin the mount, but the parent isn't mounted. The solution is to allow the revalidate to continue and perform the mount as no directory creation (at mount time) is needed for browsable mount entries.

2005-06-22[PATCH] autofs4: post expire race fixIan Kent1-0/+7
At the tail end of an expire it's possible for a process to enter autofs4_wait, with a waitq type of NFY_NONE but find that the expire is finished. In this cause autofs4_wait will try to create a new wait but not notify the daemon leading to a hang. As the wait type is meant to delay mount requests from revalidate or lookup during an expire and the expire is done all we need to do is check if the dentry is a mountpoint. If it's not then we're done. Signed-off-by: Ian Kent <raven@themaw.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-22[PATCH] Avoiding mmap fragmentationWolfgang Wander3-0/+5
Ingo recently introduced a great speedup for allocating new mmaps using the free_area_cache pointer which boosts the specweb SSL benchmark by 4-5% and causes huge performance increases in thread creation. The downside of this patch is that it does lead to fragmentation in the mmap-ed areas (visible via /proc/self/maps), such that some applications that work fine under 2.4 kernels quickly run out of memory on any 2.6 kernel. The problem is twofold: 1) the free_area_cache is used to continue a search for memory where the last search ended. Before the change new areas were always searched from the base address on. So now new small areas are cluttering holes of all sizes throughout the whole mmap-able region whereas before small holes tended to close holes near the base leaving holes far from the base large and available for larger requests. 2) the free_area_cache also is set to the location of the last munmap-ed area so in scenarios where we allocate e.g. five regions of 1K each, then free regions 4 2 3 in this order the next request for 1K will be placed in the position of the old region 3, whereas before we appended it to the still active region 1, placing it at the location of the old region 2. Before we had 1 free region of 2K, now we only get two free regions of 1K -> fragmentation. The patch addresses thes issues by introducing yet another cache descriptor cached_hole_size that contains the largest known hole size below the current free_area_cache. If a new request comes in the size is compared against the cached_hole_size and if the request can be filled with a hole below free_area_cache the search is started from the base instead. The results look promising: Whereas 2.6.12-rc4 fragments quickly and my (earlier posted) leakme.c test program terminates after 50000+ iterations with 96 distinct and fragmented maps in /proc/self/maps it performs nicely (as expected) with thread creation, Ingo's test_str02 with 20000 threads requires 0.7s system time. Taking out Ingo's patch (un-patch available per request) by basically deleting all mentions of free_area_cache from the kernel and starting the search for new memory always at the respective bases we observe: leakme terminates successfully with 11 distinctive hardly fragmented areas in /proc/self/maps but thread creating is gringdingly slow: 30+s(!) system time for Ingo's test_str02 with 20000 threads. Now - drumroll ;-) the appended patch works fine with leakme: it ends with only 7 distinct areas in /proc/self/maps and also thread creation seems sufficiently fast with 0.71s for 20000 threads.

2005-06-22[PATCH] smp_processor_id() cleanupIngo Molnar1-3/+3
This patch implements a number of smp_processor_id() cleanup ideas that Arjan van de Ven and I came up with. The previous __smp_processor_id/_smp_processor_id/smp_processor_id API spaghetti was hard to follow both on the implementational and on the usage side. Some of the complexity arose from picking wrong names, some of the complexity comes from the fact that not all architectures defined __smp_processor_id. In the new code, there are two externally visible symbols: - smp_processor_id(): debug variant. - raw_smp_processor_id(): nondebug variant. Replaces all existing uses of _smp_processor_id() and __smp_processor_id(). Defined by every SMP architecture in include/asm-*/smp.h. There is one new internal symbol, dependent on DEBUG_PREEMPT: - debug_smp_processor_id(): internal debug variant, mapped to smp_processor_id(). Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new lib/smp_processor_id.c file. All related comments got updated and/or clarified. I have build/boot tested the following 8 .config combinations on x86: {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT} I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other architectures are untested, but should work just fine.)
