* | Support for v1.10 (latest) of RISC-V privilege specification.Ruslan Bukin2017-08-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New version is not compatible on supervisor mode with v1.9.1 (previous version). Highlights: o BBL (Berkeley Boot Loader) provides no initial page tables anymore allowing us to choose VM, to build page tables manually and enable MMU in S-mode. o SBI interface changed. o GENERIC kernel. FDT is now chosen standard for RISC-V hardware description. DTB is now provided by Spike (golden model simulator). This allows us to introduce GENERIC kernel. However, description for console and timer devices is not provided in DTB, so move these devices temporary to nexus bus. o Supervisor can't access userspace by default. Solution is to set SUM (permit Supervisor User Memory access) bit in sstatus register. o Compressed extension is now turned on by default. o External GCC 7.1 compiler used. o _gp renamed to __global_pointer$ o Compiler -march= string is now in use allowing us to choose required extensions (compressed, FPU, atomic, etc).

* hyperv: Add VF bringup scripts and devd rules.Sepherosa Ziehau2017-07-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | How network VF works with hn(4) on Hyper-V in non-transparent mode: - Each network VF has a cooresponding hn(4). - The network VF and the it's cooresponding hn(4) have the same hardware address. - Once the network VF is up, e.g. ifconfig VF up: o All of the transmission should go through the network VF. o Most of the reception goes through the network VF. o Small amount of reception may go through the cooresponding hn(4). This reception will happen, even if the the cooresponding hn(4) is down. The cooresponding hn(4) will change the reception interface to the network VF, so that network layer and application layer will be tricked into thinking that these packets were received by the network VF. o The cooresponding hn(4) pretends the physical link is down. - Once the network VF is down or detached: o All of the transmission should go through the cooresponding hn(4). o All of the reception goes through the cooresponding hn(4). o The cooresponding hn(4) fallbacks to the original physical link detection logic. All these features are mainly used to help live migration, during which the network VF will be detached, while the network communication to the VM must not be cut off. In order to reach this level of live migration transparency, we use failover mode lagg(4) with the network VF and the cooresponding hn(4) attached to it. To ease user configuration for both network VF and non-network VF, the lagg(4) will be created by the following rules, and the configuration of the cooresponding hn(4) will be applied to the lagg(4) automatically.

To do per-cpu stats, convert all fields that previously were maintained in the vmmeters that sit in pcpus to counter(9). - Since some vmmeter stats may be touched at very early stages of boot, before we have set up UMA and we can do counter_u64_alloc(), provide an early counter mechanism: o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter. o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter, so that at early stages of boot, before counters are allocated we already point to a counter that can be safely written to. o For sparc64 that required a whole dummy pcpu[MAXCPU] array. Further related changes: - Don't include vmmeter.h into pcpu.h. - vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit, to match kernel representation. - struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion.

* Fully handle the special encoding of GOT[1] on mips64.John Baldwin2017-02-231-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS ABI does not require the second GOT entry to be reserved for use by the runtime linker as on other architectures. Instead, static linkers use a special value in the second GOT entry to indicate if the entry is reserved. This value is supposed to consist of an address with the MSB set and the rest of the bits all zero which is an invalid user address. However, the old binutils currently in the tree uses the 32-bit mask value (2^31) on 64-bit MIPS instead of 2^63. This was fixed in upstream binutils in 2008 to use 2^63 on 64-bit MIPS. The first part of this change changes the runtime check in init_pltgot() to check for both values (2^31 and 2^63) when deciding whether to store the current object pointer in GOT[1] which fixes dynamic N64 binaries compiled with modern binutils. However, the initial version of this fix exposed another related bug in that _rtld_relocate_nonplt_self() was only checking for the new value (2^63) in GOT[1] and incorrectly treated GOT[1] as a local GOT entry (and did not relocate the final local GOT entry). To handle this, fix all of the places that check for GOT[1]'s status to use the same macro that checks for both values on N64.

* Try to fix the old "he capability is stupid" bug in gettytab(5)/getty(8)Alexey Dokuchaev2017-02-022-52/+48
| | | | | | | | | | | | | | | | | | | | | | | | | There is one capability explicitly documented in gettytab(5) as stupid: he. And it is indeed. It was meant to facilitate system hostname modification, but is hardly usable in practice because it allows very limited editing (e.g., it depends on a particular hostname length, making it non-generic). Replace it with simple implementation that treats ``he'' as POSIX extended regular expression which is matched against the hostname. If there are no parenthesized subexpressions in the pattern, entire matched string is used as the final hostname. Otherwise, use the first matched subexpression. If the pattern does not match, the original hostname is not modified. Using regex(3) gives more freedom, does not complicate the code very much, and makes a lot more sense, in turn making ``he'' less stupid and actually useful (e.g., it is now possible to obtain node or domain names from the original hostname string, without knowing it in advance).
