rtld-audit.7: Fix (typo) error in la_pltenter() description
...
s/la_pltenter()/la_pltexit()/
la_pltenter() is called regardless of the value of
framesizep but la_pltexit() is called only if la_pltenter()
returns with non-zero framesizep set. I spent long time to
figure out why la_pltexit() is not called at all.
Quoting comments in glibc/sysdeps/x86_64/dl-trampoline.h:
/* There's nothing in the frame size, so there
will be no call to the _dl_call_pltexit. */
and
/* At this point we need to prepare new stack for the function
which has to be called. We copy the original stack to a
temporary buffer of the size specified by the 'framesize'
returned from _dl_profile_fixup */
I think it's because it needs to preserve 'inregs' to be passed to
la_pltexit().
The _dl_profile_fixup() sets the '*framesizep' to maximum value of
what la_pltenter() sets. Please see glibc/elf/dl-runtime.c file.

nptl.7: Note that i386 and x86-64 binaries can't share mutexes
...
Quoting Nicholas Miell:
PTHREAD_PROCESS_SHARED says any thread with access to the
memory containing the mutex can operate on the mutex and
POSIX basically ignores the idea that different processes
could be running completely incompatible executables or
whatever.
pthread_mutex_t has a bunch of #ifdefs in the middle of it
that change the structure size and layout between i386 and
x86_64.
Most importantly, the positions of the __nusers and __kind
fields are swapped (this looks to be an oversight dating
back to 2003 when __nusers was first introduced and carefully
preserved when the separate i386 and x86_64 versions of
pthreadtypes.h were merged into the single x86 version),
which means that when the lock and unlock functions attempt
to figure out what kind of mutex it is
(recursive/adaptive/whatever), they'll look at the wrong
field if the mutex is from the wrong architecture and then
things will break.
And then there's the fact that the rest of the struct is a
union in the 32-bit version and flat in the 64-bit version,
but that could have been worked around if you put a flag in
the __kind field that tells the 64-bit pthread library that
it is looking at a 32-bit mutex.

rtld-audit.7: Use correct printf() specifier for pointer types
...
In the example code you used %x rather than %p in the example
code for an audit library. The problem is that it truncates the
pointers on 64b platforms. So you get something like:
la_symbind64(): symname = strrchr sym->st_value = 0x7f4b8a3f8960
ndx = 222 flags = 0x0 refcook = 8b53e5c8 defcook = 8b537e30
rather than:
la_symbind64(): symname = fclose sym->st_value = 0x7fa452dd49b0
ndx = 1135 flags = 0x0 refcook = 0x7fa453f395c8 defcook = 0x7fa453f32e30
This has bitten me a handful of times when playing around with
audit test libraries to investigate its behavior.

packet.7: Add sll_protocol to list of required fields for outbound packets
...
The manpage packet(7) currently states that:
"When you send packets it is enough to specify sll_family, sll_addr,
sll_halen, sll_ifindex."
This is incorrect: you also need to specify sll_protocol.
(The protocol specified when the socket is created is used for
filtering inbound packets, but not for constructing outbound
packets.)
I encountered this while researching a page for my website:
http://www.microhowto.info/howto/send_an_arbitrary_ethernet_frame_using_an_af_packet_socket_in_c.html
To empirically verify the behaviour I took my test code from the
above page then changed it to use different values for the third
argument to socket() and the sll_protocol field:
- socket created with ETH_P_ARP, packet sent with ETH_P_ARP:
packet sent with EtherType of ETH_P_ARP
- socket created with ETH_P_ARP, sll_protocol==0:
packet sent with EtherType of 0
- socket created with 0x88b5, sll_protocol==htons(ETH_P_ARP):
packet sent with EtherType of ETH_P_ARP
- socket created with ETH_P_ARP, sll_protocol==htons(0x88b5):
packet sent with EtherType of 0x88b5
This shows that leaving sll_protocol set to zero does not have
the desired effect and that it needs to be set to the desired
link-layer protocol.
There is code in the relevant kernel source file
(net/packet/af_packet.c) which appears to inspect the value of the
sll_protocol field and use it as the link-layer protocol number,
however I am not sufficiently familiar with this subsystem to be
fully confident of what is happening. The line in question is:
proto = saddr->sll_protocol;
In version 3.4 of the kernel this can be found in the functions
packet_snd and tpacket_snd. In version 2.6.26 it is in packet_sendmsg.
Below is a patch that adds sll_protocol to the list of required fields.
This may not be the whole truth, since it is not clear what role if any
sll_protocol, sll_halen or sll_addr would play when the socket type is
SOCK_RAW, however I'm confident it is more accurate than the page as it
stands at present.

bootparam.7: Remove crufty SCSI device driver options
...
[Part of a general change to remove cruft from this page.]
Much of the detail on device-driver specifics in this page dates
from the 20th century. (The last major update to this page was in
man-pages-1.14!) It's hugely out of date now (many of these
devices disappeared from the kernel years ago.) Arguably, this
kind of detail should never have been placed in a man page to
begin with, since devices come and go. Remove such text, and
where appropriate and possible add pointers to files in the
kernel Documentation/ directory.

"xattr" is a more meaningful name than "attr" (it resonates
with the names of the system calls), so as long as we are
moving the page to a new section, we'll change the name as well,
and retain an acl(5) link so that old references remain valid.

attr.7: Document EA limits for Btrfs
...
From experimentation, I found a 16kB limit on name + value +
overhead bytes. Digger deeper, I see that
https://btrfs.wiki.kernel.org/index.php/Project_ideas#Unlimited_extended_attributes
says:
Unlimited extended attributes
Not claimed — no patches yet — Not in kernel yet
Currently size of value of an extended attribute must fit into
inline space (~3900 on 4k leaf size), while other filesystems
do not limit the size. Add a new b-tree item to hold the xattr
value in extents.
And reading mkfs.btrfs(8) reveals that the default node (AKA leaf)
size is 16kB.

tcp.7: Document removal of TCP_SYNQ_HSIZE
...
Looking over the man page for 'tcp' I came across a reference to
tuning the 'TCP_SYNQ_HSIZE' parameter when increasing
'tcp_max_syn_backlog' above 1024. However, this static sizing was
removed back in Linux 2.6.20 in favor of dynamic scaling - as
part of commit 72a3effaf633bcae9034b7e176bdbd78d64a71db.
I have included a patch below with reference to this commit, and
that the process detailed is not required on >= Linux 2.6.20.

user_namespaces.7: Update the documentation to reflect the fixes for negative groups
...
Files with access permissions such as rwx---rwx give fewer
permissions to their group then they do to everyone else. Which
means dropping groups with setgroups(0, NULL) actually grants a
process privileges.
The unprivileged setting of gid_map turned out not to be safe
after this change. Privileged setting of gid_map can be
interpreted as meaning yes it is ok to drop groups. [ Eric
additionally noted: Setting of gid_map with privilege has been
clarified to mean that dropping groups is ok. This allows
existing programs that set gid_map with privilege to work
without changes. That is, newgidmap(1) continues to work
unchanged.]
To prevent this problem and future problems, user namespaces were
changed in such a way as to guarantee a user can not obtain
credentials without privilege that they could not obtain without
the help of user namespaces.
This meant testing the effective user ID and not the filesystem
user ID, as setresuid(2) and setregid(2) allow setting any process
UID or GID (except the supplementary groups) to the effective ID.
Furthermore, to preserve in some form the useful applications
that have been setting gid_map without privilege, the file
/proc/[pid]/setgroups was added to allow disabling setgroups(2).
With setgroups(2) permanently disabled in a user namespace, it
again becomes safe to allow writes to gid_map without privilege.

Clarify that tcp_tw_recycle will break communication with many
general-purpose remote Internet hosts (namely, remote NAT devices)
even when the Linux device itself is not behind NAT.
Sources:
- BCP to make NAT implementors aware of this problem (2013):
https://tools.ietf.org/html/draft-penno-behave-rfc4787-5382-5508-bis-04#section-3.1.2
- RFC 1323 (PAWS)
- RFC 6191: Reducing the TIME-WAIT State Using TCP Timestamps

communicating with the general-purpose Internet:

epoll.7: Use epoll_create1() rather than epoll_create() in the code example

epoll_create1() is more or less the preferred API for new
applications, since it allows for some flags and avoids the
misdesigned epoll_create() argument, and so it seems sensible
to use that in the example, rather than epoll_create().

fanotify.7: fanotify notifies only events generated on the same mount
...
Unfortunately, fanotify does not inform listeners for all paths
under which a touched filesystem object is visible, but only the
listener using the same path as the process touching the
filesystem object.

ascii.7: Charset pages unification, minor cleanups
...
This and the follow-up patches will provide unification of
charset pages, minor cleanups, and some unifying cosmetic
changes. References are adjusted so that all pages include
a reference to charsets(7), which contains a description of
these sets, stray comments are removed, some obsolete
statements (like ISO 8859-1 being the de-facto ASCII
replacement) are removed, and some minor reformatting
to minimize diff's between the pages are done.
The actual substance, the character tables, remain unchanged.
This series changes the following pages (under man7): ascii,
armscii, cp1251, koi8-r, koi8-u, and all of iso_8859-*.
