* igc(4): Introduce new driver for the Intel I225 Ethernet controller.Peter Grehan2021-07-122-0/+169
| | | | | | | | | | | | | | | | This controller supports 2.5G/1G/100MB/10MB speeds, and allows tx/rx checksum offload, TSO, LRO, and multi-queue operation. The driver was derived from code contributed by Intel, and modified by Netgate to fit into the iflib framework. Thanks to Mike Karels for testing and feedback on the driver.

* Pass the syscall number to capsicum permission-denied signalsDavid Chisnall2021-07-101-0/+2
| | | | | | | | | | | | | | | The syscall number is stored in the same register as the syscall return on amd64 (and possibly other architectures) and so it is impossible to recover in the signal handler after the call has returned. This small tweak delivers it in the `si_value` field of the signal, which is sufficient to catch capability violations and emulate them with a call to a more-privileged process in the signal handler.

* pf: fallback if $pf_rules fails to loadThomas Steen Rasmussen2021-07-081-1/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | Support loading a default pf ruleset in case of invalid pf.conf. If no pf rules are loaded pf will pass/allow all traffic, assuming the kernel is compiled without PF_DEFAULT_TO_DROP, as is the case in GENERIC. In other words: if there's a typo in the main pf_rules we would allow all traffic. The new default rules minimise the impact of this. If $pf_program (i.e. pfctl) fails to set $pf_fules and $pf_fallback_rules_enable is YES we will load $pf_fallback_rules_file if set, or $pf_fallback_rules. $pf_fallback_rules can include multiple rules, for example to permit traffic on a management interface. $pf_fallback_rules_enable defaults to "NO", preserving historic behaviour. man page changes by ceri@.

* EFI RT: resurrect EFIIOC_GET_TABLEPavel Balaev2021-07-031-3/+20
| | | | | | | | | | | | | | | | | | | | | | Make it work, but change the interface to be safe for non-root users. In particular, right now interface only works for the tables which can be minimally parsed by kernel to determine the table size. Then, userspace can query the table size, after that it provides a buffer of needed size and kernel copies out just table to userspace. Main advantage is that user no longer need to be able to read /dev/mem, the disadvantage is the need to have minimal parsers aware of the table types. Right now the parsers are implemented for ESRT and PROP tables. Future extension of the present interface might be a return of only the table physical address, in case kernel does not have suitable parser yet. Then, a privileged user could read the table from /dev/mem. This extension, which logically equivalent to the old (non-worked) EFIIOC_GET_TABLE variant, is not implemented until needed.

See hptrr(4) for an example. * Also, we have broken links in our Release Notes. This is a consequence of the first point. See https://www.freebsd.org/releases/13.0R/hardware/#proc-i386.

| | | | | | | | | | | | | | | | | | | | ENETC it a gigabit Ethernet controller found on the LS1028A board. It supports basic VLAN offloads - tag extraction, injection and hardware filtering. Inband MDIO connectivity is used for link status monitoring through the miibus interface. Fixed-link mode is also supported, which allows for operation of internal cpu to switch port. Since no admin interrupts are present in hardware, link status polling has to be used. Due to a hardware bug software reset of the NIC results in a external abort. Because of that most of the hardware initialization is done during attach. This also means that in the case of an fatal error full board reset is required. The enetc_hw.h header was imporoted from Linux. It is dual licensed.

The caller is also in charge of any memory allocation and/or expansion that's needed during this process. Create a bus_generic_child_{pnpinfo,location} and make it default. It just returns success. This is for those busses that have no information for these items. Migrate the now-empty routines to using this as appropriate.

* fdescfs: add an option to return underlying file vnode on lookupKonstantin Belousov2021-06-041-13/+81
| | | | | | | | | | | | | | | | | | | | | | | The 'nodup' option forces fdescfs to return real vnode behind file descriptor instead of the fdescfs fd vnode, on lookup. The end result is that e.g. stat("/dev/fd/3") returns the stat data for the underlying vnode, if any. Similarly, fchdir(2) works in the expected way. For open(2), if applied over file descriptor opened with O_PATH, it effectively re-open that vnode into normal file descriptor which has the specified access mode, assuming the current vnode permissions allow it. If the file descriptor does not reference vnode, the behavior is unchanged. This is done by a mount option, because permission check on open(2) breaks established fdescfs open semantic of dup(2)-ing the descriptor. So it is not suitable for /dev/fd mount.
