struct kern_ipc_perm.deleted is meant to be used as a boolean toggle, and the changes introduced by this patch are just to make the case explicit. Signed-off-by:

Rafael Aquini authored
After the locking semantics for the SysV IPC API got improved, a couple of IPC_RMID race windows were opened because we ended up dropping the 'kern_ipc_perm.deleted' check performed way down in ipc_lock(). The spotted races got sorted out by re-introducing the old test within the racy critical sections. This patch introduces ipc_valid_object() to consolidate the way we cope with IPC_RMID races by using the same abstraction across the API implementation. Signed-off-by:

When trying to understand semop code, I found a small mistake in the check for semadj (undo) value overflow. The new undo value is not stored immediately and next potential checks are done against the old value. The failing scenario is not much practical. One semop call has to do more operations on the same semaphore. Also semval and semadj must have different values, so there has to be some operations without SEM_UNDO flag. For example: struct sembuf depositor_op[1]; struct sembuf collector_op[2]; depositor_op[0].sem_num = 0; depositor_op[0].sem_op = 20000; depositor_op[0].sem_flg = 0; collector_op[0].sem_num = 0; collector_op[0].sem_op = -10000; collector_op[0].sem_flg = SEM_UNDO; collector_op[1].sem_num = 0; collector_op[1].sem_op = -10000; collector_op[1].sem_flg = SEM_UNDO; if (semop(semid, depositor_op, 1) == -1) { perror("Failed to do 1st deposit"); return 1; } if (semop(semid, collector_op, 2) == -1) { perror("Failed to do 1st collect"); return 1; } if (semop(semid, depositor_op, 1) == -1) { perror("Failed to do 2nd deposit"); return 1; } if (semop(semid, collector_op, 2) == -1) { perror("Failed to do 2nd collect"); return 1; } return 0; It passes without error now but the semadj value has overflown in the 2nd collector operation.

Commit da29bd36 ("mm/mm_init.c: make creation of the mm_kobj happen earlier than device_initcall") changed to pure_initcall(mm_sysfs_init). That's too early: mm_sysfs_init() depends on core_initcall(ksysfs_init) to have made the kernel_kobj directory "kernel" in which to create "mm". Make it postcore_initcall(mm_sysfs_init). We could use core_initcall(), and depend upon Makefile link order kernel/ mm/ fs/ ipc/ security/ ... as core_initcall(debugfs_init) and core_initcall(securityfs_init) do; but better not.

Revert commit ece86e22, which was intended as a small performance improvement. Despite the claim that the patch doesn't introduce any functional changes in fact it does. The "no page" path behaves different now. Originally, vmalloc_to_page might return NULL under some conditions, with new implementation it returns pfn_to_page(0) which is not the same as NULL. Simple test shows the difference. test.c #include <linux/kernel.h> #include <linux/module.h> #include <linux/vmalloc.h> #include <linux/mm.h> int __init myi(void) { struct page *p; void *v; v = vmalloc(PAGE_SIZE); /* trigger the "no page" path in vmalloc_to_page*/ vfree(v); p = vmalloc_to_page(v); pr_err("expected val = NULL, returned val = %p", p); return -EBUSY; } void __exit mye(void) { } module_init(myi) module_exit(mye) Before interchange: expected val = NULL, returned val = (null) After interchange: expected val = NULL, returned val = c7ebe000 Signed-off-by:

In original __alloc_memory_core_early() for bootmem wrapper, we do not align size silently. We should not do that, as later free with old size will leave some range not freed. It's obvious that code is copied from memblock_base_nid(), and that code is wrong for the same reason. Also remove that in memblock_alloc_base. Signed-off-by:

Dave reported big numa system booting is broken. It turns out that commit 5b6e5295 ("x86: memblock: set current limit to max low memory address") sets the limit to low wrongly. max_low_pfn_mapped is different from max_pfn_mapped. max_low_pfn_mapped is always under 4G. That will memblock_alloc_nid all go under 4G. Revert 5b6e5295 to fix a no-boot regression which was triggered by 457ff1de ("lib/swiotlb.c: use memblock apis for early memory allocations").

Pull user namespaces work from Eric Biederman: "The work to convert the kernel to use kuid_t and kgid_t has been finished since 3.12 so it is time to remove the scaffolding that allowed the work to progress incrementally. The first patch on this branch just removes the scaffolding, ensuring we will always get compile errors if people accidentally try the userspace and the kernel uid and gid types. The second patch an overlooked and unused chunk of mips code that that fails to build after the first patch. The code hasn't been in linux-next for long (as I was out of it and could not sheppared the cold properly) but the patch has been around for a long time just waiting for the day when I had finished the uid/gid conversions. Putting the code in linux-next did find the compile failure on mips so I took the time to get that fix reviewed and included. Beyond that I am not too worried about errors because all these two patches do is delete a modest amount of code" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: MIPS: VPE: Remove vpe_getuid and vpe_getgid userns: userns: Remove UIDGID_STRICT_TYPE_CHECKS
