SIOCGAIRONET allows userspace to query an(4) for various device properties and configuration, which appears to potentially include sensitive information such as WEP keys (an(4) seems to predate WPA). Also avoid races by copying in the request structure to a temporary buffer before locking and modifying the device softc.

2018-09-26Reapply, with minor tweaks, r338025, from the original commit:Warner Losh
Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change. Mostly done with the coccinelle 'spatch' tool: $ cat modpnpsize0.cocci @normaltables@ identifier b,c; expression a,d,e; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,d, -sizeof(d[0]), e); @singletons@ identifier b,c,d; expression a; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,&d, -sizeof(d), 1); $ rg -l MODULE_PNP_INFO -- sys | \ xargs spatch --in-place --sp-file modpnpsize0.cocci (Note that coccinelle invokes diff(1) via a PATH search and expects diff to tolerate the -B flag, which BSD diff does not.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

2015-01-06In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson
socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

2013-08-12Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCIScott Long
command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

Submitted by: avatar Notes: svn path=/head/; revision=175446
2008-01-18First real attempt at proper locking. The locking is a little complicatedDoug Ambrisko
since the the command and data that is being built to be sent to or read from the HW lives in the softc. Commands are later run via an_setdef etc. In the ioctl path various references are kept to the data stored in the softc so it needs to be protected. Almost think of the command in the softc a global variable since it essentially is. Since locking wasn't done in this type of context the commands would get corrupted. Thanks to avatar@ for catching some lock issues and dhw@ for testing. Things are a lot more stable except for the MPI-350 cards. My an(4) remote laptop stays on the network now. The driver should be changed so that it uses private memory that is passed to the functions that talk to the card. Then only those functions would really need to grab locks.
