2016-08-12mmap.2: Describe treatment of 'offset' for MAP_ANONYMOUSJann Horn1-3/+6
The manpage claimed that the offset argument is ignored, and when I interpreted that as "I don't need to set that register when doing the syscall", I got failures. I was able to spot two reasons for that: What I probably ran into: At least on x86-64, sys_mmap (in arch/x86/kernel/sys_x86_64.c) always checks that the offset is page-aligned, even for MAP_ANONYMOUS. Another one, could probably trigger on 32-bit x86: In do_mmap(), there is a check to ensure that pgoff together with the allocation length won't cause an overflow, even for MAP_ANONYMOUS. Document that userspace should pass in zero, since that's probably what everyone is doing already. (It would also be possible to describe the constraints on the offset more carefully, but zero works, and nobody should need to pass in anything else.) Signed-off-by: Jann Horn <jann@thejh.net>

2016-07-16console_ioctl.4: The argument to KDGETMODE is an 'int'Michael Kerrisk1-2/+2
As reported by Chris:i The manual entry for KDGETMODE specifies "argp points to a long which is set to one of the above values." At least on x86_64-bit Fedora24, the text should probably specify argp is an int (32-bit), rather than a long (64-bit). [To verify:] Open a file descriptor to the local console, and execute some code like the following: long arg = -1; if (-1 == ioctl(fd, KDGETMODE, &arg)) { return -1; } printf("KDGETMODE: 0x%lx\n", arg); Now try this version: int arg = -1; if (-1 == ioctl(fd, KDGETMODE, &arg)) { return -1; } printf("KDGETMODE: 0x%x\n", arg); Result: The first version gives this result: KDGETMODE: 0xffffffff00000001 The second version gives this result: KDGETMODE: 0x1 Reading the kernel source confirms this point.

2016-07-12getauxval.3: Correct AT_HWCAP result descriptionCownie, James H1-2/+3
The getauxval(3) man page describes the result for AT_HWCAP as "A pointer to a multibyte mask of bits", however the actual value returned is not a pointer, but simply the first 32 bits of the capabilities mask. This can be observed directly. Note the value shown for AT_HWCAP is a 32 bit value that is not a pointer (see AT_PHDR or AT_RANDOM for how pointers are shown). % LD_SHOW_AUXV=1 cat < /dev/null AT_SYSINFO_EHDR: 0x7fffe89fe000 AT_HWCAP: bfebfbff AT_PAGESZ: 4096 AT_CLKTCK: 100 AT_PHDR: 0x400040 AT_PHENT: 56 AT_PHNUM: 9 AT_BASE: 0x0 AT_FLAGS: 0x0 AT_ENTRY: 0x402634 AT_UID: 515 AT_EUID: 515 AT_GID: 114 AT_EGID: 114 AT_SECURE: 0 AT_RANDOM: 0x7fffe8917be9 AT_EXECFN: /usr/bin/cat AT_PLATFORM: x86_64

The perf_output_sample_ustack in kernel/events/core.c only writes a single 64 bit word if it can't dump the user registers. From the current version of the man page, I would have expected two 64 bit words (one for size, one for dyn_size). Change the man page to make this behavior explicit.

The license on the original versoin of this page is troublesome, because of restrictions imposed by the clause that the page may be modified "for the purpose of improving Linux or its documentation efforts". By now, I have rewritten all except trivial pieces of the page, and the structure definitions in any case came from kernel header files. So, I'm relicensing the page to the "verbatim" license.

2016-07-07capabilities.7: Note on SECURE_NO_CAP_AMBIENT_RAISE for capabilities-only ↵Michael Kerrisk1-0/+2
environment A few months after applying Andy Lutomirski's patch that documented ambient capabilities, I found myself again asking a question that I'd already once asked of Any. So, best to be more explicit in the man page that setting/locking SECBIT_NO_CAP_AMBIENT_RAISE is not required when using prctl(PR_SET_SECUREBITS) to create a capabilities-only environment. This was the 4 Dec 2015 reply from Andy to my question: > In the capabilities(7) page tehre is the longstanding text: > > An application can use the following call to lock itself, and > all of its descendants, into an environment where the only way > of gaining capabilities is by executing a program with associ‐ > ated file capabilities: > > prctl(PR_SET_SECUREBITS, > SECBIT_KEEP_CAPS_LOCKED | > SECBIT_NO_SETUID_FIXUP | > SECBIT_NO_SETUID_FIXUP_LOCKED | > SECBIT_NOROOT | > SECBIT_NOROOT_LOCKED); > > As far as I can estimate, no changes are needed here to include > SECBIT_NO_CAP_AMBIENT_RAISE and SECBIT_NO_CAP_AMBIENT_RAISE_LOCKED > in the above prctl() call, but could you confirm please? Correct. I'll probably write up a patch to suggest that doing this is a poor idea on a conventional distro, though, and I'll explain why. I suppose than deleting this would be an option, too.

2016-07-07getitimer.2: Change license to note that page may be modifiedMichael Kerrisk1-1/+1
The page as originally written carried text that said the page may be freely distributed but made no statement about modification. In the 20+ years since it was first written, the page has in fact seen repeated, sometimes substantial, modifications, and only a small portion of the original text remains. One could I suppose rewrite the last few pieces that remain from the original, but as the largest contributor to the pages existing text, I'm just going to relicense it to explicitly note that modification is permitted. (I presume the failure by the original author to grant permission to modify was simply an oversight; certainly, the large number of people who have changed the page have taken that to be the case.)
