2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds8-19/+6
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of vmlinux.bin, the actual uncompressed kernel binary. Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF vmlinux), which is bigger than vmlinux.bin. As a result, vmlinuz was loaded into a memory address higher then actually needed - a problem for small memory platforms.

2010-10-01MN10300: Fix flush_icache_range()David Howells1-1/+19
flush_icache_range() is given virtual addresses to describe the region. It deals with these by attempting to translate them through the current set of page tables. This is fine for userspace memory and vmalloc()'d areas as they are governed by page tables. However, since the regions above 0x80000000 aren't translated through the page tables by the MMU, the kernel doesn't bother to set up page tables for them (see paging_init()). This means flush_icache_range() as it stands cannot be used to flush regions of the VM area between 0x80000000 and 0x9fffffff where the kernel resides if the data cache is operating in WriteBack mode. To fix this, make flush_icache_range() first check for addresses in the upper half of VM space and deal with them appropriately, before dealing with any range in the page table mapped area. Ordinarily, this is not a problem, but it has the capacity to make kprobes and kgdb malfunction. It should not affect gdbstub, signal frame setup or module loading as gdb has its own flush functions, and the others take place in the page table mapped area only.

Commit c52c2ddc1dfa ("alpha: switch osf_sigprocmask() to use of sigprocmask()") had several problems. The more obvious compile issues got fixed in commit 0f44fbd297e1 ("alpha: fix compile problem in arch/alpha/kernel/signal.c"), but it also caused a regression. Since _BLOCKABLE is already the set of signals that can be blocked, the code should do "newmask & _BLOCKABLE" rather than inverting _BLOCKABLE before masking.

2010-09-29um: Proper Fix for f25c80a4: remove duplicate structure field initializationBoaz Harrosh1-14/+3
uml_net_set_mac() was broken and luckily it was never used, before. What it was trying to do is spin_lock before memcopy the mac address. Linus attempted to fix it in assumption that someone decided the lock was needed. But since it was never ever used at all, and was just dead code, I think we can assume that it is not needed, after all. On the other hand patch [f25c80a4] was trying to use eth_mac_addr() in eth_configure(), *which was the real fallout*. Because of state checks done inside eth_mac_addr() the address was never set. I have not reintroduced the memcpy wrapper, but I've put a comment for future cats. The code now is back to exactly as it was before [f25c80a4]. With the cleanup applied. If the spin_lock is indeed needed then a contender should supply a test case that fails, then fix it with the proper locking, as a separate unrelated patch.

2010-09-28MN10300: Handle missing sys_cacheflush() when caching disabledDavid Howells2-8/+27
When caching is disabled on the MN10300 arch, the sys_cacheflush() function is removed by conditional stuff in the makefiles, but is still referred to by the syscall table. Provide a null version that just returns 0 when caching is disabled (or -EINVAL if the arguments are silly).
