+ Michael Kerrisk
+ Fix some imprecisions in discussion of namespaced file capabilities
+ The file UID does not come into play when creating a v3
+ security.capability extended attribute.
+ Michael Kerrisk
+ Note that v3 security.attributes are transparently created/retrieved
+ Michael Kerrisk
+ Improve the discussion of when file capabilities are ignored
+ The text stated that the execve() capability transitions are not
+ performed for the same reasons that setuid and setgid mode bits
+ may be ignored (as described in execve(2)). But, that's not quite
+ correct: rather, the file capability sets are treated as empty
+ for the purpose of the capability transition calculations.
+ Michael Kerrisk
+ Rework bounding set as per-thread set in transformation rules
+ Michael Kerrisk
+ Substantially rework "Capabilities and execution of programs by root"
+ Rework for improved clarity, and also to include missing details
+ on the case where (1) the binary that is being executed has
+ capabilities attached and (2) the real user ID of the process is
+ not 0 (root) and (3) the effective user ID of the process is 0
+ (root).
+ Marcus Gelderie
+ Add details about SECBIT_KEEP_CAPS
+ The description of SECBIT_KEEP_CAPS is misleading about the
+ effects on the effective capabilities of a process during a
+ switch to nonzero UIDs. The effective set is cleared based on
+ the effective UID switching to a nonzero value, even if
+ SECBIT_KEEP_CAPS is set. However, with this bit set, the
+ effective and permitted sets are not cleared if the real and
+ saved set-user-ID are set to nonzero values.
+ Marcus Gelderie
+ Mention header for SECBIT constants
+ Mention that the named constants (SECBIT_KEEP_CAPS and others)
+ are available only if the linux/securebits.h user-space header
+ is included.

+ Michael Kerrisk
+ Rework discussion of exec and UID 0, correcting a couple of details
+ Clarify the "Capabilities and execution of programs by root"
+ section, and correct a couple of details:
+ * If a process with rUID == 0 && eUID != 0 does an exec,
+ the process will nevertheless gain effective capabilities
+ if the file effective bit is set.
+ * Set-UID-root programs only confer a full set of capabilities
+ if the binary does not also have attached capabilities.
+ Michael Kerrisk
+ Update URL for libcap tarballs
+ The previous location does not seem to be getting updated.
+ (For example, at the time of this commit, libcap-2.26
+ had been out for two months, but was not present at

+ Michael Kerrisk
+ Reframe the text on delegation to include more details about cgroups v1
+ Michael Kerrisk [Leah Hanson]
+ Rework discussion of writing to cgroup.type file
+ In particular, it is possible to write "threaded" to a
+ cgroup.type file if the current type is "domain threaded".
+ Previously, the text had implied that this was not possible.
+ Michael Kerrisk [Balbir Singh, Marcus Gelderie]
+ Soften the discussion about delegation in cgroups v1
+ Balbir pointed out that v1 delegation was not an accidental
+ feature.

+epoll.7

+ Michael Kerrisk
+ Consistently use the term "interest list" rather than "epoll set"
+ Michael Kerrisk
+ Reformat Q&A list
+ Michael Kerrisk
+ Note that edge-triggered notification wakes up only one waiter
+ Note a useful performance benefit of EPOLLET: ensuring that
+ only one of multiple waiters (in epoll_wait()) is woken
+ up when a file descriptor becomes ready.
+ Michael Kerrisk
+ Expand the discussion of the implications of file descriptor duplication
+ In particular, note that it may be difficult for an application
+ to know about the existence of duplicate file descriptors.

+ IP_RECVTTL error fixed
+ I need to get the TTL of UDP datagrams from userspace, so I set

+pid_namespaces.7
+ Michael Kerrisk
+ Clarify the semantics for the adoption of orphaned processes
+ Because of setns() semantics, the parent of a process may reside
+ in the outer PID namespace. If that parent terminates, then the
+ child is adopted by the "init" in the outer PID namespace (rather
+ than the "init" of the PID namespace of the child).
+ Michael Kerrisk
+ Note a detail of /proc/PID/ns/pid_for_children behavior
+ After clone(CLONE_NEWPID), /proc/PID/ns/pid_for_children is empty
+ until the first child is created. Verified by experiment.
+ Michael Kerrisk
+ Note that a process can do unshare(CLONE_NEWPID) only once

+ Helge Deller
+ Add signal numbers for parisc
+ Michael Kerrisk
+ Unify signal lists into a signal table that embeds standards info
+ Having the signals listed in three different tables reduces

+ Michael Kerrisk
+ Reorder the architectures in the signal number lists
+ x86 and ARM are the most common architectures, but currently
+ are in the second subfield in the signal number lists.
+ Instead, swap that info with subfield 1, so the most
+ common architectures are first in the list.
+ Michael Kerrisk
+ Place signal numbers in a separate table
