add glob information to the word structure so we wont accidently
deglob quoted strings containing the GLOB. we store Globsize(word)
in in word->glob which avoids recalculating that values and the
check if a word should be globbed quick.
globlist() now substitutes the word inplace avoiding the copying
when all words are literals and avoids recursion.
minor cleanups: use list2str() in execeval(), move octal() to
unix.c, remove the (char*) casts to efree().
when using rio auto-complete to resolve file names for the "attach:" and
"include:" headers, the auto-completer might leave whitespaces at
the end of the line which leads upas/marshal to not find the file.
it is now possible to configure additional interfaces (like wifi)
and store the network information while preserving old entries
in /net/ndb. this allows to easily switch from ethernet to wifi
and have dhcp configure dns without having to clear /net/ndb.
Probably the temporary solution to obtain the Estonian uppercase Š and Ž [S and Z with caron (ˇ)] without Shift + AltGr, I note in https://code.9front.org/hg/plan9front/rev/5b6853beadb4 you've written a Shift + AltGr (table 7) for Polish, would be using the caron (ˇ) mapped to key 41 followed by Shift s or Shift z; it was a mistake to earlier map a mode 4 in my fix of /sys/lib/kbmap/ee. It is a bit of an inconvenience to have an AltGr mapping to š and ž, but not a Shift + AltGr mapping to Š and Ž, but that's the best I can do for now. I send a new ee file without the mode 4.

these should not be in here

netmkaddr() can return a the pointer to the host string if
it is already a full dial string. but we assumed to get
a copy and freed it before returning.
when _syserrno() fails to map a plan9 error string to
a unix error number, we copy the plan9 error string
to the per process error buffer "plan9err" and set
errno = EPLAN9.
when strerror() is called with EPLAN9, it returns
a pointer to the plan9err buffer.
I introduced a regression in sed that currently has screwed up
/sys/lib/man/secindex.
The issue is that sed 's/$/ foo/g' will actually replace the newline
character with foo instead of just appending at the end of the line.
This only makes a difference when sed is operating on a multiple line
record. The effect is a record like:
foo
bar
baz
becomes:
foo foobar foo baz foo
instead of
foo foo
bar foo
baz foo
problem is NaN() produces a SNaN, not a QNaN... and on the 387,
storing 80 bit SNaN in register to a 64-bit memory destination
traps.
SNaN/QNaN encoding is machine specific. mips has the qiet/signaling
bit inverted.
disabling fp exception in main() now, but that sucks.
i think the best solution would be to not even call strtod() in
is_number() but just write a regex or a little state machine that
will only accept numbers without nan and ±inf.
that might even make it faster and is more robust than relying on
the os's strtod() details.
if the input string contains invalid utf-8, runetochar() produces
unicode replacement characters that can overflow the literal buffer.
as the overflow check is done after runetochar(), add UTFmax bytes
of slack space avoiding the issue.
silly clients (web*) reconnect when the handshake failed with a lower
protocol version, which allows downgrade attacks (POODLE). but instead
of stopping this madness, they invented a new magic TLSID to indicate
to the server that this connection attempt is a retry, and rely on the
server to notice and stop them from sabotaging themselfs.
implement ECDHE key exchange with secp256r1 on the server side, providing
perfect forward secrecy (tho slowly).
it is easier to just keep the ECDH/DH state in the TlsSec structure,
which fits better with the grouping of the functions. we do the cleanup
in tlsConnectionFree() now, so a lot of error handling logic could go
away.
reinvestigated some error paths and removed the ones that cannot error.
move functions to fit the logical grouping.
combine the code for signing handshake hashes (for client certs) and
DH parameters. provide digestDHparams() function to be shared between
server and client code.
don't pass or generate sessionID's. this was never used nor
actually implemented and leaks the process pid.
get rid of version and random field duplications, move TlsSec
structure into TlsConnection.
make msgRecv() clear the message first, get rid of unneccesary
msgClear() calls.
instead of letting factotum_rsa_open() parse the certificate,
we pass in the rsa public key which is then matched against the
factotum keyring. this avoids parsing the x509 certificate
twice.
the sec->rsapub was not freed, so free it in tlsSecClose()
- dirpackage() was not checking if the stat entry lies within
the buffer. fixed.
- simplify dirpackage(), as we process all the bytes from
the buffer, we do not need to track "ss" here as its the same
as "ts".
- zero Dir* array pointer early in dirread() and dirreadall()
and avoid calling dirpackage on <= buffer length.
The /sys/lib/kbmap/ee file seemed to have CRs in it. If a first column in the table
(for modifier key) as 4 is for Alt Gr + Shift then the attached (UTF-8 without BOM)
should work as a replacement ee file.

assigning the expression value to a temporary variable in
BPSHORT() and BPLONG() saves arround 2K of text in rio on
arm and arround 1K on amd64.
loadchar(): use the passed in "h" as the char index instead
of recomputing it from c-f->cache. dont recompute wid.
cachechars(): do cache lookup and find oldest entry in a
single loop pass.
the openssl we currently use is outdated and will be removed
soon. webfs will handle the https for us with native tls code.
keys have to be stored in factotum for everyone who also wants
to commit directly.
This patch is only an adaptation for 9front of the patch located in
http://www.9legacy.org/9legacy/patch/pc-ether82563-i210.diff. The
major difference is that this patch ignores errors in checksum of
eeprom, because in my system the checksum was wrong. After 3 months,
I didn't have problems, and I think the patch can be used. although
it has some things that need to be fixed. If the link is inactive
when the system boots then it will remain inactive forever.

Hi all,
In plan9port this bug keeps crashing mc when I run lc in a directory with Chinese characters. This is a diff from OpenBSD but it should apply cleanly to the various plan9 sources.
The code is basically trying to do a realloc (I guess realloc wasn't available back then?) but it copies too much from the original buffer.
Since realloc is available, just use it. If realloc isn't available outside plan9port (I haven't checked) the memmove line should be changed from:
memmove(f->subf, of, (f->nsubf+DSUBF)*sizeof *subf);
to:
memmove(f->subf, of, f->nsubf*sizeof *subf);
I hope this is helpful.
Ray
