Among other things, Jann pointed out that the commoncap LSM is always invoked, and Kees Cook pointed out the relevant kernel code: === > BTW, can you point me at the piece(s) of kernel code that show that > "commoncap" is always invoked in addition to any other LSM that has > been installed? It's not entirely obvious, but the bottom of security/commoncap.c shows: struct security_hook_list capability_hooks[] = { LSM_HOOK_INIT(capable, cap_capable), ... }; void __init capability_add_hooks(void) { security_add_hooks(capability_hooks, ARRAY_SIZE(capability_hooks)); } And security/security.c shows the initialization order of the LSMs: int __init security_init(void) { pr_info("Security Framework initialized\n"); /* * Load minor LSMs, with the capability module always first. */ capability_add_hooks(); yama_add_hooks(); loadpin_add_hooks(); /* * Load all the remaining security modules. */ do_security_initcalls(); return 0; } === Reported-by: Jann Horn <jann@thejh.net> Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>

2016-06-29ptrace.2: Clarify the purpose of mentioning the kernel PTRACE_MODE_* constantsMichael Kerrisk1-0/+11
The "ptrace access mode" text is about user-space-visible behavior, but in order to explain that behavior at what I believe is a sufficient level of detail (e.g., to differentiate the various types of checks that are performed for various system calls and pseudofile accesses), one needs (1) to discuss the MODE flag details as implemented in the kernel, and (2) to have a shorthand way to refer to the various cases from other pages. It's not absolutely necessary to name the flags for (1), but using the flag names is certainly a handy shorthand for (2). Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>

Since we now know that glibc does not support all the keywords mentioned in ISO/IEC TR 14652 [1] and in general glibc aims to be conforming to POSIX first and foremost, I think it's best just to drop the reference to ISO/IEC TR 14652 from the man page. 1) http://www.open-std.org/jtc1/SC22/WG20/docs/n972-14652ft.pdf After this I think the locale related man pages are finally as complete as they need to be.
2016-06-14locale.5: Document missing keywords, minor updatesMarko Myllynen1-15/+28
Cross-checked the current locale.5 page against glibc locales and fixed the following issues: - mention define/ifdef/else/endif - mention reorder-sections-{after,end} - mention script - section/section-symbol are not used, only mentioned in the ISO TR - Fix int_currency_symbol -> int_curr_symbol typo - few formatting fixes
2016-06-14charmap.5: Clarify keyword syntaxMarko Myllynen1-10/+10
Updates charmap(5) to match the syntax all the glibc charmap files are using currently.
2016-06-14locale.5, repertoiremap.5: Clarify keyword syntaxMarko Myllynen2-7/+15
All the glibc locale/repertoiremap files use the format described in the patch. The fix is trivial (and adds an example just in case), I presume these were copypasted from charmaps.5 page, all the glibc charmaps use slightly different format for keywords (I'll send a separate patch to address charmaps.5 next).

iBoth add_key and the utility "keyctl add" return EINVAL when attempting to add a user key with an empty or NULL payload. The manpage implies that this should be valid. From my reading of the kernel source, this has not been possible since at least linux kernel commit 1da177e4 (2.6.12-rc2 on 2005-04-16). Until kernel commit cf7f601c, security/keys/user_defined.c:user_instantiate returned -EINVAL if datalen <= 0.

2016-05-29strcasecmp.3: Make details of strncasecmp() comparison clearerMichael Kerrisk1-6/+5
Quoting Ori: The manpage for strncasecmp has a few wording issues that can be improved: 1) In the DESCRIPTION section, "except it compares only the first n bytes of s1" s1 can be shorter than n bytes. Consider adding "(at most)" after "first". For comparison with reference materials, POSIX uses the wording "not more than n bytes", OSX and FreeBSD use "compares at most [...]". 2) In the RETURN VALUE section: "if s1 (or the first n bytes thereof) is found [...] to match [...] s2" This could theoretically be read to suggest that the first n bytes of s1 are compared against the FULL s2, which is not the case. Consider removing the parenthetical altogether (thus, not mentioning 'n' at all). POSIX doesn't mention 'n' in its RETURN VALUE section. 3) The RETURN VALUE section doesn't mention case insensitivity. It's in the DESCRIPTION, but perhaps it should also be in this section. POSIX mentions case-insensitivity in RETURN VALUE. Consider adding "and ignoring case" after "respectively".

2016-05-29recv.2: With pending 0-length datagram read() and recv() with flags == 0 differMichael Kerrisk1-2/+16
Quoting Tom: The statement "With a zero flags argument, recv() is equivalent to read(2)." is not correct. In the case of passing a UDP socket an empty buffer the two calls differ. read(2) will be a noop (as it rightly says in its manpage), but recv(2) will discard the packet. We ran into this in networkd, as we use FIONREAD to determine the buffer size (and allocate the right buffer), so in case someone passed us an empty packet we would end up in a busy loop when we were using read(2). Changing to recv(2) fixed the issue [https://github.com/systemd/systemd/pull/3299]. Reported-by: Tom Gundersen <teg@jklm.no> Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
