| New and rewritten pages |
| ----------------------- |
| |
| pkey_alloc.2 |
| Dave Hansen [Michael Kerrisk] |
| New page documenting pkey_alloc(2) and pkey_free(2) |
| |
| pthread_getattr_default_np.3 |
| Michael Kerrisk |
| New page documenting pthread_getattr_default_np(3) and pthread_setattr_default_np(3) |
| |
| strfromd.3 |
| Wainer dos Santos Moschetta |
| New page documenting strfromd(3), strfromf(3), and strfroml(3) |

| New page describing /dev/fuse |
| This is my writeup of a basic description of /dev/fuse after |
| playing with it for a few hours today. It is of course woefully |
| incomplete, and since I neither have a use case nor am working |
| on this code, I will not be in a position to expand it in the |
| near future. However, I'm hoping this could still serve as a |
| handy reference for others looking at this interface. |
| |
| [mtk: Notwithstanding the incompleteness of this page, |
| it's a good base for future extension.] |
| |

| |
| accept.2 |
| Michael Kerrisk |
| Remove editorializing comments about 'socklen_t' |
| Michael Kerrisk |

| TID before clone() returns to user space |
| |
| close.2 |
| Michael Kerrisk [Daniel Wagner] |
| Rework and greatly extend discussion of error handling |
| Further clarify that an error return should be used only |
| for diagnostic or remedial purposes. |
| Michael Kerrisk |
| Other UNIX implementations also close the FD, even if reporting an error |
| Looking at some historical source code suggests |
| that the "close() always closes regardless of error return" |
| behavior has a long history, predating even POSIX.1-1990. |
| Michael Kerrisk |
| Note that future POSIX plans to require that the FD is closed on error |
| See http://austingroupbugs.net/view.php?id=529#c1200. |
| Michael Kerrisk |
| Clarify the variation in EINTR behavior per POSIX and other systems |
| |
| fallocate.2 |
| Darrick J. Wong |
| Document behavior with shared blocks |
| Note that FALLOC_FL_UNSHARE may use CoW to unshare blocks to |
| guarantee that a disk write won't fail with ENOSPC. |
| |
| fanotify_mark.2 |
| Heinrich Schuchardt |
| Mention FAN_Q_OVERFLOW |
| To receive overflow events it is necessary to set this bit |
| in fanotify_mark(). |
| |
| fcntl.2 |
| Michael Kerrisk |
| F_GETPIPE_SZ allocates next power-of-2 multiple of requested size |
| Add some detail about current implementation, since this helps |
| the user understand the effect of the user pipe limits added in |
| Linux 4.5 (described in pipe(7)). |
| Michael Kerrisk |
| Add EPERM that occurs for F_SETPIPE_SZ when user pipe limit is reached |
| |
| fideduperange.2 |
| Darrick J. Wong [Omar Sandoval] |
| Fix the discussion of maximum sizes |
| Fix the discussion of the limitations on the dest_count and |
| src_length parameters to the fideduperange ioctl() to reflect |
| what's actually in the kernel. |
| |
| fsync.2 |
| Michael Kerrisk |
| SEE ALSO: add fileno(3) |
| fileno(3) is useful if one is combining fflush(3)/fclose(3) |
| and fsync(2). |
| Michael Kerrisk |
| SEE ALSO: add fflush(3) |
| |
| getgroups.2 |
| Andrew Clayton |
| FTM requirements fix for setgroups(2) |
| |
| gethostname.2 |
| Michael Kerrisk |
| SEE ALSO: add hostname(1) |
| |
| get_mempolicy.2 |
| Michael Kerrisk |
| Note that 'addr' must be NULL when 'flags' is 0 |
| |
| getpriority.2 |
| Michael Kerrisk |
| Warn that autogrouping voids the effect of 'nice' in many cases |
| Refer the reader to sched(7) for the details. |
| Michael Kerrisk |
| Expand discussion of getpriority() return value |
| Michael Kerrisk |
| The nice value supplied to setpriority() is clamped |
| Note that the nice value supplied to setpriority() is clamped |
| to the permitted range. |
| Michael Kerrisk |
| Improve description of setpriority() return value |
| |
| getpriority.2 |
| sched.7 |
| Michael Kerrisk |
| Move nice value details from getpriority(2) to sched(7) |
| Centralizing these details in sched(7) is more logical. |
| |
| getrandom.2 |
| random.4 |
| Michael Kerrisk |
| Consolidate and improve discussion on usage of randomness |
| Currently, recommendations on how to consume randomness are |
| spread across both getrandom(2) and random(4) and the general |
| opinion seems to be that the text in getrandom(2) does a |
| somewhat better job. Consolidate the discussion to a single |
| page (getrandom(2)) and address some of the concerns |
| expressed about the existing text in random(4). |
| [Some of this text ultimately made its way into the new |
| random(7) page.] |
| |
| getrandom.2 |
| Michael Kerrisk |
| Remove material incorporated into random(7) |
| Michael Kerrisk |
| Note advantages of fact that getrandom() doesn't use file descriptors |

| Michael Kerrisk |
| Warn that autogrouping voids the effect of 'nice' in many cases |
| Michael Kerrisk |
| CONFORMING TO: Remove an ancient SVr4 detail on errno values |

| Michael Kerrisk |
| Rework formatting of /proc interfaces |
| Make the information easier to parse by formatting the file |
| descriptions as hanging lists. No significant content changes. |
| Nikos Mavrogiannopoulos [Laurent Georget] |
| Provide a more accurate description of /dev/urandom |
| This documents the "property" of /dev/urandom of being able to |
| serve numbers prior to pool being initialized, and removes any |
| suggested usages of /dev/random which are disputable |
| (i.e., one-time pad). Document the fact /dev/random is only |
| suitable for applications which can afford indeterminate delays |
| since very few applications can do so. Smooth the alarming |
| language about a theoretical attack, and mention that its |
| security depends on the cryptographic primitives used by the |
| kernel, as well as the total entropy gathered. |
| Michael Kerrisk [Laurent Georget, Theodore Ts'o] |
| Improve discussion of /dev/urandom, blocking reads, and signals |
| The text currently states that O_NONBLOCK has no effect for |
| /dev/urandom, which is true. It also says that reads from |
| /dev/urandom are nonblocking. This is at the least confusing. |
| If one attempts large reads (say 10MB) from /dev/urandom |
| there is an appreciable delay, and interruption by a signal |
| handler will result in a short read. Amend the text to |
| reflect this. |
| |
| elf.5 |
| Mike Frysinger |
| Add subsection headers at major points |
| The current pages dumps all the content into one big DESCRIPTION |
| with no real visual break up between logically independent |
| sections. Add some subsection headers to make it easier to |
| read and scan. |
| Mike Frysinger |
| Document notes |
| Document the Elf{32,64}_Nhdr structure, the sections/segments that |
| contain notes, and how to interpret them. I've been lazy and only |
