[PATCH v1 00/21] man/man2/*: Update history of syscalls H-M

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 4736 bytes --]

Hi all,

This set updates the history of system calls H to M.

While I have been thorough with my research, I would encourage those
interested to double-check that my edits make sense given the listed
sources.  Particularly for linkat(2), SEEK_DATA/SEEK_HOLE, mkdirat(2),
and mincore(2), since they took significantly more time and research
than other functions.

[PATCH v1 03/21] man/man2/link.2: HISTORY: Change order of linkat(2)

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 1767 bytes --]

glibc 2.4 released on 2006-03-06.[1]  Linux 2.6.16 released on
2006-03-20.[2]  So chronologically list glibc before Linux.

POSIX.1-2008 released in 2008 (shocker!).  However, glibc's addition of
linkat(2) on 2005-12-16 declared the function in posix/unistd.h,[3]
implying it was known (or at least suspected) to have been proposed for
inclusion in POSIX.1-2008.[4]  So chronologically list POSIX before
glibc.

[PATCH v1 06/21] man/man2/lseek.2: HISTORY: Update appearances of SEEK_{DATA,HOLE}

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 2792 bytes --]

SEEK_DATA and SEEK_HOLE appeared in Solaris no later than 2005-12-12,
when a ZFS developer stated in a blog post that "[a]t this [time of]
writing, SEEK_HOLE and SEEK_DATA are Solaris-specific."[1]  The release
notes for Solaris 10 are dated to 2005-12.[2]  So the constants were
likely added in Solaris 10.

They were added to FreeBSD on 2007-04-05,[3] before being released in
FreeBSD 7.0 - the release notes stating that "[s]upport for Sun's ZFS
has been added" for amd64, i386, and pc98.[4]

They were also added to DragonFly BSD on 2009-04-07,[5] before being
released in DragonFly BSD 2.3.1 (which strangely seems to have no
release notes).[6]

The commit adding the constants to DragonFly BSD states that the commit
contents were obtained from FreeBSD.[5]  So chronologically FreeBSD is
listed before DragonFly BSD.  And the commit adding them to FreeBSD
references their implementation in OpenSolaris.[3]  So chronologically
Solaris is listed before FreeBSD.

POSIX.1-2024 is also moved to the end of the list, since it was released
decades after any system discussed here.

[minor point on English usage]

Hi Seth,

At 2026-01-26T12:28:59+0000, Seth McDonald wrote:

"At this writing" is idiomatic (but relatively formal) English.

If the bracketed "[time of]" was meant only or mainly to clarify meaning
for non-native English speakers, of whom there are many subscribed to
this list, that's fine of course, and you should skip this message.

I'm having trouble finding an authoritative source for my claim, and my
_American Heritage Dictionary of Idioms_ is no use--possibly because
this isn't an idiomatic, but a literal one, if one interprets "writing"
as referring to an action in progress, like "playing" or "dancing", and
not as a gerund, as in "in my time of dying".

But here are some exhibits of its correct (idiomatic, if you will) use
on the Web.

"I also subscribe to MLB-TV and urge on my Baltimore Orioles, who
haven't had such a good time of it at this writing."
	https://www.bowdoin.edu/news/2025/06/getting-them-laughing.html

"Linney has a series of audio lectures based on The First Year of Latin,
an 1902 text by Gunnison and Harley covering, at this writing, half the
text."
	https://quarksandquirks.wordpress.com/tag/william-linney/

"The program book, still online at this writing, contained informative
program notes by musicologist Anne Piéjus, an excellent essay by
Washington Post Art and Architecture critic Philip Kennicott drawing
parallels between the French court’s reception of Esther and impacts of
today’s social media, and an also excellent essay by music historian
Benjamin Bernard who covered private school education at a
contemporaneous boys school, Collège Mazarin, and the girls school at
Saint-Cyr, Maison royae de Saint-Louis."
	https://operagene.com/new-blog/2024/2/12/opera-lafayettes-from-saint-cyr-to-cannons-moreau-and-handels-esther-theater-as-mass-media

(One's got to have an immense lung capacity to perform opera
professionally, and even its fans would seem to be up to that high
standard, judging by the prodigious length of the foregoing sentence.)

Regards,
Branden

[PATCH v1 08/21] man/man2/mincore.2: HISTORY: Update appearances of mincore(2)

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 2072 bytes --]

mincore(2) was implemented in FreeBSD on 1995-10-21,[1] which was first
included in the FreeBSD 2.2 release on 1997-03.[2]

It was implemented in NetBSD on 1999-06-15,[3] which was first included
in the NetBSD 1.5 release on 2000-12-06,[4] (despite the commit message
stating its intended inclusion in NetBSD 1.4.1).

It was implemented in OpenBSD on 2001-03-09,[5] which was first included
in the OpenBSD 2.9 release on 2001-06-01.[6]

All other listed systems are taken at face value and rearranged in

Hi Seth,

Sorry for taking so much time to respond.  I was busy with a meeting of
the C Committee.  I'm back.  I've merged already patches 01..07.

This patch seems to be corrupt.

I could manually apply it, but it's probably worth checking why this is
happening.  Probably another issue with protonmail, I guess.


Have a lovely night!

[PATCH v1 09/21] man/man2/mkdir.2: HISTORY: Change order of mkdirat(2)

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 1991 bytes --]

glibc 2.4 released on 2006-03-06.[1]  Linux 2.6.16 released on
2006-03-20.[2]  So chronologically list glibc before Linux.

POSIX.1-2008 released in 2008, adding mkdirat(2) to the
specification.[3]  glibc added mkdirat(2) on 2005-12-03,[4] and the
mailing list discussion about its addition seems to suggest it was
considered before it was known that POSIX would add it.[5]  So
chronologically list glibc (and Linux) before POSIX.

mkdir(2) seems to have appeared in 4.2BSD with the system call number
136, as seen in the system's /usr/src/sys/sys/syscalls.c file.[1]  The
function also appeared in POSIX.1-1988.[2]

[Seth McDonald]

[-- Attachment #1: Type: text/plain, Size: 1642 bytes --]

msgrcv(2) and msgsnd(2) appeared in SUSv1.[1]  The functions were added
to POSIX.1-2001 when POSIX and SUS merged, but as an XSI extension
(still SUS-only).[2][3]  And they remain as an XSI extension in
POSIX.1-2024.[4][5]

I thank you for this work!  I could not have told you that mkdir(2)--
the system call--arrived in Unix as late as 4.2BSD.  My first thought
was, "that can't be right".  My second was, "ah, that must be when Unix
got rid of the 14-character limit on file names".

(Traditionally in Unix, a directory was a plain file of 16-byte
entries--a 14-byte `char` field for the file name, which was not
null-terminated if of maximum length, and a 2-byte `int` for the file's
inode number.  This design kept the system call interface narrow.  It
also, if I understand the war stories correctly, could lead to horrible
problems, like users open(2)ing directories belonging to themselves and
trashing them with sloppy code, or introducing cycles into into the
graph of the file system by creating hard links to directories.[1])

And sure enough, history appears to record that the Berkeley FFS ("fast
file system") came in with 4.2BSD as well.

https://www.oreilly.com/openbook/opensources/book/kirkmck.html

Regards,
Branden

[1] This was such an unthinkable and invalid situation that, again AIUI,
    that rather than being flatly prohibited by the kernel, only root
    was allowed to create hard links to directories.

I've applied all patches, except the mincore.2 one (it was corrupt).
Thanks a lot!  I'll release very soon; probably tomorrow.  :)

[PATCH v2 0/1] man/man2/*: Update history of syscalls H-M

[Seth McDonald]

Hi Alex,

Apologies on my end also for my delayed response.  I've made some large
but hopefully beneficial changes to my email workflow – as can be seen
with the different email address.

> This patch seems to be corrupt. [...] Probably another issue with
> protonmail, I guess.

Yeah at this point I give up with ProtonMail.  I shouldn't have to fix
all their issues for them just to send in a patch.  Hopefully Fastmail
serves me better.

Anyhow, this is just the patch for mincore(2) with a few minor
adjustments on the commit message.  I won't PGP sign it yet as I first
want to ensure everything works before adding things on top.  But if all
is well, I'll continue to sign my patches with my more secure key:

E9D1 26A5 F0D4 9DF7 792B  C2E2 B4BF 4530 D39B 2D51

Let me know if it's still corrupt, and I'll ̶k̶i̶c̶k̶ ̶m̶y̶ ̶P̶C calmly figure out
what's going on.

[PATCH v2 1/1] man/man2/mincore.2: HISTORY: Update appearances of mincore(2)

[Seth McDonald]

mincore(2) was implemented in FreeBSD on 1995-10-21,[1] and was first
included in the FreeBSD 2.2 release on 1997-03.[2]

It was implemented in NetBSD on 1999-06-15,[3] and was first included in
the NetBSD 1.5 release on 2000-12-06,[4] (despite the commit message
stating its intended inclusion in NetBSD 1.4.1).

It was implemented in OpenBSD on 2001-03-09,[5] and was first included
in the OpenBSD 2.9 release on 2001-06-01.[6]

All other listed systems are taken at face value and rearranged in
chronological-ish order.

Thanks!  I've applied the patch.

I had to amend it with this:

	diff --git i/man/man2/mincore.2 w/man/man2/mincore.2

You can check <CONTRIBUTING.d/lint> in case you want to check these
issues.  However, I don't mind sporadic issues in patches, since my CI
catches them anyway, so I can just amend them when I find them.


Have a lovely day!

So far it works.  I could apply the patch.

I personally use Migadu <https://migadu.com/>.  I've had a very good
experience with them, and they're very quick in fixing any bugs I report
to them.  If Fastmail works fine for you, that's great!

Ok.

BTW, the ubuntu keyserver shows the existence of a non-revoked key that
is probably old?

	pub (4)eddsa263/82b9620e53d0a1ae2d696111c267b0020a900289 2024-12-06T06:53:33Z

It contains two UIDs, one of which is revoked, but the other is not
revoked:

	uid mcdonald_seth@pm.me <mcdonald_seth@pm.me>
	sig cert  c267b0020a900289 2024-12-06T06:53:33Z ____________________ ____________________ [selfsig]

	uid Seth McDonald (email encryption) <mcdonald_seth@pm.me>
	sig revok c267b0020a900289 2026-02-11T08:27:33Z ____________________ ____________________ [selfsig]

Is it intentionaly that you revoked the UID instead of the key?  If you
want to revoke the entire key, you should probably use gpg(1)'s
--gen-revoke flag, which generates a revocation certificate for the
master key.

It worked.  :)

I'm actually quite surprised I didn't come across them.  I tried looking
at every email provider (even considered Purelymail, which I believe is
currently a 2-3 person project).  Migadu do look great from their
website, so I'll keep them in mind as a good backup.

That actually was intentional.  The two signatures on my key are of the
keys I used with my Proton emails; I signed it to show that I'm indeed
the same person despite the different email address.

I added the second UID to imply that of the two keys, if someone wanted
to send me encrypted email, they should use the one whose UID states
"email encryption".  But since I'm no longer planning on those being my
main email addresses, I revoked the "email encryption" UID.  But my
Proton address does still use that key, so I didn't revoke the whole
thing.

Well that's certainly a relief!

Btw, did the strikethrough text render correctly for you?  It renders as
strikethrough for me on mutt(1) and vim(1), but it looks -l-i-k-e- 
-t-h-i-s on the lore.kernel.org archive.

Take care,

Yup, it looks correct on mutt(1) and neomutt(1).
