Make it consistent. - Michael Kerrisk [Christian Brauner, Jann Horn] - EXAMPLE: Allocate child's stack using mmap(2) rather than malloc(3) - Christian Brauner suggested mmap(MAP_STACK), rather than - malloc(), as the canonical way of allocating a stack for the - child of clone(), and Jann Horn noted some reasons why - (MAP_STACK exists elsewhere, and mmap() returns a page-aligned - block of memory, which is useful if we want to set up a guard - page at the end of the stack). - Michael Kerrisk [Christian Brauner] - Tidy up the description of CLONE_DETACHED - The obsolete CLONE_DETACHED flag has never been properly - documented, but now the discussion CLONE_PIDFD also requires - mention of CLONE_DETACHED. So, properly document CLONE_DETACHED, - and mention its interactions with CLONE_PIDFD. - Michael Kerrisk [Christian Brauner] - Give the introductory paragraph a new coat of paint - Change the text in the introductory paragraph (which was written - 20 years ago) to reflect the fact that clone*() does more things - nowadays. - Michael Kerrisk - Remove wording that suggests CLONE_NEW* flags are for containers - These flags are used for implementing many other interesting - things by now. - Michael Kerrisk - Remove various details that are already covered in namespaces pages - Remove details of UTS, IPC, and network namespaces that are - already covered in the corresponding namespaces pages in section 7. - -clone.2 -proc.5 - Michael Kerrisk - Adjust references to namespaces(7) - Adjust references to namespaces(7) to be references to pages - describing specific namespace types. - -fallocate.2 - Andrew Price - Add gfs2 to the list of punch hole-capable filesystems - -ioctl_iflags.2 - Michael Kerrisk [Robert Edmonds] - Emphasize that FS_IOC_GETFLAGS and FS_IOC_SETFLAGS argument is 'int *' - -ioctl_list.2 - Michael Kerrisk - Add reference to ioctl(2) SEE ALSO section - The referenced section lists various pages that document ioctls. - -mmap.2 - Michael Kerrisk - Note that MAP_STACK exists on some other systems - Michael Kerrisk - Some rewording of the description of MAP_STACK - Reword a little to allow for the fact that there are now - *two* reasons to consider using this flag. - -pidfd_open.2 - Michael Kerrisk - Note the waitid() use case for PID file descriptors - Michael Kerrisk - Add a subsection header "Use cases for PID file descriptors" - Michael Kerrisk - Make it a little more explicit the CLONE_PIDFD returns a PID FD - -pivot_root.2 - Michael Kerrisk - EXAMPLE: allocate stack using mmap() MAP_STACK rather than malloc() - -quotactl.2 - Yang Xu [Jan Kara] - Add some details about Q_QUOTAON - -seccomp.2 -cgroups.7 - Michael Kerrisk - Switch to "considerate language" - -select.2 - Michael Kerrisk - POLLIN_SET/POLLOUT_SET/POLLEX_SET are now defined in terms of EPOLL* - Since kernel commit a9a08845e9acbd224e4ee466f5c1275ed50054e8, the - equivalence between select() and poll()/epoll is defined in terms - of the EPOLL* constants, rather than the POLL* constants. - -wait.2 - Michael Kerrisk - waitid() can be used to wait on children in same process group as caller - Since Linux 5.4, idtype == P_PGID && id == 0 can be used to wait - on children in same process group as caller. - Michael Kerrisk - Clarify semantics of waitpid(0, ...) - As noted in kernel commit 821cc7b0b205c0df64cce59aacc330af251fa8f7, - threads create an ambiguity: what if the calling process's PGID - is changed by another thread while waitpid(0, ...) is blocked? - So, clarify that waitpid(0, ...) means wait for children whose - PGID matches the caller's PGID at the time of the call to - waitpid(). - -getauxval.3 - Michael Kerrisk [Witold Baryluk] - Clarify that AT_BASE_PLATFORM and AT_EXECFN return pointers to strings - See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=942207 - -resolv.conf.5 - Florian Weimer - Attempt clarify domain/search interaction - The domain directive is historic at this point; it should not - be used. - -netdevice.7 - Michael Kerrisk [Silviu Popescu] - Small wording fix in description of SIOCGIFCONF - SIOCGIFCONF returns "network layer" addresses (not "transport - layer"). - -uts_namespaces.7 - Michael Kerrisk - Add a little more detail on scope of UTS namespaces |
