The previous names tspec_is_int and tspec_is_uint were confusing because
there are actually tspec_t constants called INT and UINT, these
classification macros return true for other integer types as well,
though.
While here, remove the prefix "tspec_" from these macros. It wasn't as
helpful as intended, in many cases it was obviously redundant, when it
was called as tspec_is_integer(tn->tn_type->t_tspec).
No functional change.
Contrary to the comment in typeok, the types of the expressions before
promotions and conversions are not needed for SHL, SHLASS and SHRASS.
Move that code over to typeok_shr, the only place where it is actually
used. This removes another 3 variables from typeok.
The code in typeok is already complicated enough. Only few of the
checks actually examine the subtype of the pointer, the others don't
need to look at it. Therefore don't initialize the variables lstp
(left-hand side subtype) and rstp unless they are actually needed.
This reduces the number of variables in typeok and the number of
parameters to the sub-functions.
The C preprocessor does not require its arguments to be expressions, an
empty string is valid as well. This allows to replace the 0 in the
operator properties table with a space, making the 1 stick out.
Since the table is quite long, divide it into sections and add section
headers.
No change in the generated code.
The file ops.c had previously been autogenerated. This meant that in a
NetBSD build, it was generated in OBJDIR, and a build that had just
updated src/usr.bin would fail. For a build that last ran on
2020-12-01, and again today, it looks like this:
# link lint1/lint1
cc ... -o lint1 cgram.lo ... ops.lo ... tyname.lo
/usr/bin/ld: ops.lo: in function `initmtab':
ops.c:(.text+0x63): undefined reference to `STRUCT_ASSIGN'
This is caused by ops.c existing in OBJDIR, so the new version in
NETBSDSRCDIR is not looked at. To prevent this, use oper.c instead as
the filename, which has not been used before.

************************
* Support for new EAP (Extensible Authentication Protocol) methods:
- Support for EAP-TLS, from Jan Just Keijser and others
- Support for EAP-MSCHAPv2, from Eivind Næss, Thomas Omerzu, Tijs
Van Buggenhout and others
* New pppd options:
- chap-timeout
- chapms-strip-domain
- replacedefaultroute
- noreplacedefaultroute
- ipv6cp-accept-remote
- lcp-echo-adaptive
- ip-up-script
- ip-down-script
- ca
- capath
- cert
- key
- crl-dir
- crl
- max-tls-version
- need-peer-eap
* Fixes for CVE-2020-8597 and CVE-2015-3310.
* libpcap is now required when compiling on Linux (previously, if
libpcap was not present, pppd would be compiled without packet
filtering support).
* The rp-pppoe plugin has been renamed to pppoe, to distinguish it
from the upstream rp-pppoe code. Its options have changed names,
but the old names are kept as aliases.
* The configure script now supports cross-compilation.
* Many bug fixes and cleanups.
What was new in ppp-2.4.8.
**************************
* New pppd options have been added:
- ifname, to set the name for the PPP interface device
- defaultroute-metric, to set the metric for the default route
- defaultroute6, to add an IPv6 default route (with nodefaultroute6
to prevent adding an IPv6 default route)
- up_sdnotify, to have pppd notify systemd when the link is up.
* The rp-pppoe plugin has new options:
- host-uniq, to set the Host-Uniq value to send
- pppoe-padi-timeout, to set the timeout for discovery packets
- pppoe-padi-attempts, to set the number of discovery attempts.
* Added the CLASS attribute in radius packets.
* Sundry bug fixes.
* Fixed warnings and issues found by static analysis.
* Added Submitting-patches.md.
What was new in ppp-2.4.7.
**************************
* Fixed a potential security issue in parsing option files (CVE-2014-3158).
* There is a new "stop-bits" option, which takes an argument of 1 or 2,
indicating the number of stop bits to use for async serial ports.
* Various bug fixes.
What was new in ppp-2.4.6.
**************************
* Man page updates.
* Several bug fixes.
* Options files can now set and unset environment variables for
scripts.
* The timeout for chat scripts can now be taken from an environment
variable.
* There is a new option, master_detach, which allows pppd to detach
from the controlling terminal when it is the multilink bundle master
but its own link has terminated, even if the nodetach option has
been given.
The initial page table code enters mappings first through an identity
mapped normal-NC mapping. Then later on, additional mappings are added
through a KVA-mapped normal-WB mapping. There is a warning about this
in the Armv8 ARM:
Bytes written without the Write-Back cacheable attribute within the
same Write-Back granule as bytes written with the Write-Back cacheable
attribute might have their values reverted to the old values as a result
of cache Write-Back.
Change the identity mapping attributes to match the KVA-mapping. This
fixes an issue where the kernel often doesn't start under ESXi-Arm Fling.
Several of the tests only need to add the -p flag. Mentioning the
(current) default flags in each of these tests is redundant. Therefore,
allow them to specify "lint1-extra-flags: -p" instead of the current
"lint1-flags: -g -S -w -p".
If lint is run on a platform that has CHAR_BIT == 10, this doesn't
magically make an ILP32 platform have 40 bits per uint32_t.
At the moment, all of the supported platforms are either ILP32 or
I32LP64 anyway, and all of them have CHAR_BIT == 8 == CHAR_SIZE,
so nothing changes practically.
