  • 6a03552381 Distinguish between ENOMEM (as representing a lack of internal memory as allocated by malloc()) versus all other errors, in particular ENOBUFS (representing a lack of external buffer space, e.g. in a device's TX queue or a user buffer). Michael Brown 2007-01-11 16:30:21 +00:00
  • 143e3b84a4 Downloaded from current grub CVS. Michael Brown 2007-01-11 16:22:03 +00:00

  • c6c63d954d Rename "image" field to "data", because "image->image" is just confusing. Michael Brown 2007-01-11 16:07:30 +00:00

  • 7ad1c2eaa8 Removed the Etherboot-specific ELF-image code and replaced it with a generic ELF loader, to be used by the multiboot code. Michael Brown 2007-01-11 14:44:03 +00:00
  • 10980c12ee Add image directory back in Michael Brown 2007-01-11 14:43:15 +00:00
  • 3634e705b7 Remove osloader.c and replace with a prep_segment() that uses userptr_t and get_memmap() in image/segment.c Michael Brown 2007-01-11 14:32:26 +00:00
  • ceca6b185c Added user_to_phys() and memset_user(). Michael Brown 2007-01-11 14:27:27 +00:00
  • c980cdd0aa Move memmap.h out of arch/i386; it no longer contains anything architecture-dependent and is needed by the ELF code. Michael Brown 2007-01-11 14:08:44 +00:00

  • 037da9d840 I hate NULL pointer dereferences. Michael Brown 2007-01-11 05:27:02 +00:00
  • 03390f0cd6 Use pkb_pad() rather than doing it the dangerous way :) Michael Brown 2007-01-11 05:26:16 +00:00
  • a3ed0cbbc7 Extract packet-padding login from rtl8139.c to a separate pkbpad.c file. Michael Brown 2007-01-11 05:25:50 +00:00

  • c0ef730ec4 Fix bug in buffer.c, add buffer mini-unit test. Michael Brown 2007-01-11 04:46:41 +00:00
  • 83fa318b86 Added strerror(0)=="No error", so that TCP protocols can use strerror(rc) in their closed() methods without producing "Error 0x0000" when the connection is closed normally. Michael Brown 2007-01-11 04:01:31 +00:00
  • e2dcd05b67 Update buffer-handling code to enable expandable buffers. Michael Brown 2007-01-11 03:50:47 +00:00
  • bb2024c6d6 Move include/buffer.h to include/gpxe/buffer.h Michael Brown 2007-01-11 01:47:26 +00:00
  • de042993c0 Warn when net device on an active route is not open. Michael Brown 2007-01-10 20:58:36 +00:00
  • d45c5e7ce7 Add "route" command (which currently only displays the routing table; it can't modify it). Michael Brown 2007-01-10 20:51:14 +00:00
  • d9ba8f790b Add route() function to display routing table. Michael Brown 2007-01-10 20:38:20 +00:00
  • 78ded6604a Try booting from the "boot" network device first (i.e. the one which we were loaded from). The code to identify this device isn't present yet, but the code to act upon the knowledge is. Michael Brown 2007-01-10 20:21:42 +00:00
  • 1fa5cd0e2b Add find_pci_netdev() Michael Brown 2007-01-10 16:16:05 +00:00
  • fdc97499bf Add device description fields to struct device. Michael Brown 2007-01-10 15:27:48 +00:00
  • 489a4004d7 Give UNDI device a more meaningful name. Michael Brown 2007-01-10 05:52:04 +00:00
  • f396f1f9d3 Force ordering of commands within help list. Michael Brown 2007-01-10 05:13:20 +00:00
  • cef551376f Force ordering of commands in help list. Michael Brown 2007-01-10 05:10:30 +00:00
  • 77bb7b13a7 Having forced __table() to natural structure alignment, it now seems that we *can* place arrays in tables, which means we can force the order within a table without having to resort to explicitly numbered sections on everything. Michael Brown 2007-01-10 05:08:05 +00:00
  • dad5274522 Add "name" field to struct device to allow human-readable hardware device names. Michael Brown 2007-01-10 04:22:09 +00:00
  • cc9b32c405 Remove uIP; we haven't used it for quite some time now. Michael Brown 2007-01-10 02:52:58 +00:00
  • 753e156844 Allow udp_{send,sendto,sendto_via} to be called outside of the udp_senddata() callback. This will simplify any UDP protocols that don't need the temporary buffer. Michael Brown 2007-01-10 02:46:39 +00:00
  • 649b789e93 DHCP transmits via specified net device, so no need to create a dummy routing table entry just to fool ipv4.c any more. Michael Brown 2007-01-10 02:37:23 +00:00
  • c821a7b20d Add udp_sendto_via() to allow e.g. DHCP to transmit without first having to set up dummy routing entries. Michael Brown 2007-01-10 02:31:38 +00:00
  • f008b77ba2 Allow an explicit network device to be specified for IP-layer transmissions. Michael Brown 2007-01-10 02:25:11 +00:00

  • d24b80acf2 Added network interface management commands Michael Brown 2007-01-10 01:55:07 +00:00
  • 98b6154c3e Add "name" field to network device, to facilitate netdev commands. Michael Brown 2007-01-09 23:48:18 +00:00
  • c65fae2475 Add RX quotas to the net device poll() method. This avoids the problem of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left idle for a long time at the C:\ prompt and builds up a huge packet backlog. Michael Brown 2007-01-09 21:47:01 +00:00
  • e822bc2a90 Autopadding was sometimes overwriting the struct list_head at the end of the packet buffer. Although pkbuffs are guaranteed to be at least PKB_ZLEN bytes long, there's no guarantee that the data starts at the start of the packet buffer. Michael Brown 2007-01-09 21:01:55 +00:00
  • 18e5353bed Rename pkb_available() to pkb_tailroom() for consistency with Linux's skb_tailroom(). Add pkb_headroom(). Michael Brown 2007-01-09 20:56:31 +00:00
  • b7fcfe8ece Added net device TX queue; this will be needed to support the PXE UNDI API (which will need us to wait for TX completions). Michael Brown 2007-01-09 20:18:31 +00:00
  • 8a268073a7 Move start/stop/expire debug messages to DBG2() level. Michael Brown 2007-01-09 17:39:52 +00:00
  • 3c2cc59d25 Added ability to break ISR processing over several calls to poll(). This will allow us to implement RX quotas. Michael Brown 2007-01-09 17:04:10 +00:00
  • aa7bda7b47 Send EOI after enabling interrupt, in case the device had asserted IRQ to the PIC while it was disabled. Michael Brown 2007-01-09 14:53:19 +00:00
  • a2ffe8c123 Allow boot sector to completely destroy real-mode stack, but still manage to return control. Michael Brown 2007-01-09 14:13:59 +00:00
  • a9369bb503 Leave protected-mode return address on PM stack when issuing a real_call(), rather than moving it to the RM stack and back again. This allows the real-mode function to completely destroy the stack contents, provided that it manages to return to real_call(). Michael Brown 2007-01-09 14:13:06 +00:00
  • 2eeb7c4fe7 Define "connected" as Michael Brown 2007-01-09 05:01:22 +00:00
  • 70cc3a164a Reset character attributes before start of welcome banner, in case it's a serial console and remembers state from the previous program run. Michael Brown 2007-01-09 04:51:27 +00:00
  • aaca21a2b6 We can't assert that the RX engine is idle in iscsi_done(), because it may be called during the RX data processor, before the RX engine transitions back to idle. It doesn't really matter if the RX engine isn't idle when iscsi_done() is called, because it will just pick up where it left off on the next call. (The same is not true for the TX engine, so keep the TX engine assertion.) Michael Brown 2007-01-09 04:42:23 +00:00
  • 6ea07b9247 Use debug auto-colourisation. Michael Brown 2007-01-09 04:38:39 +00:00
  • 76525294ee Clean up connection closing and permanent failure logic. Michael Brown 2007-01-09 04:31:33 +00:00
  • 2738bdf74b Obsoleted by drivers/net/undionly.c Michael Brown 2007-01-09 03:22:11 +00:00
  • d606edb41d Added UNDI root bus driver (which saves including all the PCI bus code, UNDI ROM code etc. when you just want a "undi.kpxe"-type image). Michael Brown 2007-01-09 03:20:22 +00:00
  • 159930862f Added missing call to undinet_remove() Michael Brown 2007-01-09 03:08:01 +00:00
  • 6b09dd8244 undipci_probe() has to calculate busdevfn anyway, so we may as well pass it directly to undi_load_pci(). Michael Brown 2007-01-09 02:58:07 +00:00
  • ed44e3730d Avoid erasing non-existent signatures in undi_unload() Michael Brown 2007-01-09 02:53:24 +00:00
  • a2be828a33 Avoid leaving preloaded_undi with invalid PXENV+/!PXE structure addresses if the signature checks fail. Michael Brown 2007-01-09 02:52:28 +00:00
  • 697bcc9d24 Since we now always unload the base code stack (even if we keep UNDI), we can never return to the PXE stack and must always use INT 18. Michael Brown 2007-01-09 02:46:58 +00:00
  • f2f492a536 If preloaded device matches, use that rather than going via the UNDI loader. Michael Brown 2007-01-09 02:32:06 +00:00
  • 2436dac281 Populate preloaded_undi device when applicable. Michael Brown 2007-01-09 02:29:54 +00:00
