2014-09-15datapath: Improve robustness of this_cpu_ptr definition in compat layerAndy Zhou
Current autoconfig detection logic for HAVE_PER_CPU_PTR is not robust. Depends on linux kernel version, the definition can be in either linux/percpu.h or asm/percpu.h Turns out it is simpler and safer to handle missing percpu.h definitions in linux/percpu.h rather than asm/percpu.h. With this change, there is no need for the autoconfig detection logic above. Signed-off-by: Andy Zhou <azhou@nicira.com> Acked-by: Pravin B Shelar <pshelar@nicira.com>

2014-07-01datapath: Change u64_stats_* to use _irq instead of _bh().Jesse Gross
The upstream u64_stats API has been changed to remove the _bh() versions and switch all consumers to use IRQ safe variants instead. This was done to be safe for netpoll generated packets, which can occur in hard IRQ context. From a safety perspective, this doesn't directly affect OVS since it doesn't support netpoll. However, this change has been backported to older kernels so OVS needs to use the new API to compile.

2014-06-25datapath: Rehash 16-bit skbuff hashes into 32 bits.Jesse Gross
Currently, if the network stack provides skb->rxhash then we use it, otherwise we compute our own. However, on at least some versions of RHEL/CentOS, the stack provides a hash that is 16 bits rather than 32 bits. In cases where we use the uppermost bits of the hash this is particularly bad because we detect that a hash is present and we use it rather than computing our own but the result is always zero. This is particularly noticible with tunnel ports that use the hash to generate a source port, such as VXLAN. On these kernels the tunnel source port is always the minimum value. To solve this problem while still taking advantage of the precomputed hash, this rehashes the hash so that the entropy is spread throughout 32 bits.

2014-05-19acinclude.m4: Fix "sparse", via detection of GNU make "if" directive.Ben Pfaff
Make treats tabs very differently from spaces at the beginning of a line, so this test must use a tab instead of a space. This partially reverts commit a0903134d2d60 (acinclude.m4: Expand tabs).

2014-03-05Makefile: Compile Linux-specific files based on __linux__ macro.Ben Pfaff
We want to conditionally compile several files based on whether we're building for a Linux host, so we need some Automake conditional for that. Previously this was based on whether Netlink is available and we're not on ESX (since ESX has Netlink but isn't Linux), but it's more straightforward to just test for Linux directly.

2013-12-17openvswitch: Use libtool and allow building shared libsHelmut Schaa
Currently openvswitch builds all libraries static only. However, libopenvswitch is linked into nearly all openvswitch executables making it hardly possible to run openvswitch on embedded devices (for example running OpenWrt). Convert openvswitch to use libtool for building its internal libs. This allows "--enable-shared" and "--enable-static" as configure arguments. Default is "--disable-shared" thus keeping the current behavior with the only change that static libs are installed by "make install". Since the openvswitch library interfaces are internal and thus not stable (yet) encode the openvswitch version into the library name: libopenvswitch-2.0.90.so Binary size is reduced to around 1/3 when using shared libs.

This reverts commit 752378e1cd1f133a8366fbacec3b281a45ff8268 (datapath: rhel: Account for RHEL specific backports). Change related to netif_needs_gso() is cuasing panic on RHEL and Xen platforms. This way we revert back to use of ovs skb_gso_segment() and netif_skb_features() which has required compat code for gso for kernel older than 2.6.38. <1>[ 924.855722] BUG: unable to handle kernel NULL pointer dereference at 000000a0 <1>[ 924.855789] IP: [<f0337fb7>] netdev_send+0x77/0x340 [openvswitch] <4>[ 924.855849] *pdpt = 000000011bc66027 *pde = 0000000000000000 <0>[ 924.855895] Oops: 0000 [#1] SMP <0>[ 924.855927] last sysfs file: /sys/class/net/lo/carrier <4>[ 924.856551] Pid: 17937, comm: vif Not tainted (2.6.32.43-0.4.1.xs1.6.10.734.170748xen #1) VMware Virtual Platform <4>[ 924.856618] EIP: 0061:[<f0337fb7>] EFLAGS: 00010246 CPU: 0 <4>[ 924.856659] EIP is at netdev_send+0x77/0x340 [openvswitch] <4>[ 924.856697] EAX: 00000000 EBX: dd4fb800 ECX: 00000000 EDX: 00000289 <4>[ 924.856749] ESI: edd55a40 EDI: 000005dc EBP: df287aa8 ESP: df287a7c <4>[ 924.856790] DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0069 <0>[ 924.856825] Process vif (pid: 17937, ti=df286000 task=ee88d570 task.ti=df286000) <0>[ 924.856880] Stack: <4>[ 924.856902] 00000000 be8b9067 00000000 e9b02000 dd523ac0 dd523b50 f033aef1 b2e77c64 <4>[ 924.856966] <0> dd523ac0 ee902840 dd4fc58c df287ab8 f0336162 edd55a40 ee902840 df287ac8 <4>[ 924.857043] <0> f032d684 0000001e ee10a300 df287b34 f032d6ef 0000001c 00000000 00000000 <0>[ 924.858942] Call Trace: <4>[ 924.859553] [<f033aef1>] ? flex_array_get+0x51/0x70 [openvswitch] <4>[ 924.860189] [<f0336162>] ? ovs_vport_send+0x12/0x50 [openvswitch] <4>[ 924.860806] [<f032d684>] ? do_output+0x34/0x50 [openvswitch] <4>[ 924.861444] [<f032d6ef>] ? do_execute_actions+0x4f/0x830 [openvswitch] <4>[ 924.862047] [<f032dfa0>] ? ovs_execute_actions+0x70/0xd0 [openvswitch] <4>[ 924.862636] [<f032fd3f>] ? ovs_dp_process_received_packet+0x8f/0xf0 [openvswitch] <4>[ 924.863774] [<f033690e>] ? ovs_vport_receive+0x5e/0x70 [openvswitch] <4>[ 924.864354] [<f0337d9f>] ? netdev_frame_hook+0x4f/0x90 [openvswitch] <4>[ 924.864918] [<c034f7ab>] ? netif_receive_skb+0x1bb/0x6a0 <4>[ 924.865469] [<c03c193f>] ? vlan_gro_common+0x10f/0x230 <4>[ 924.866007] [<c034fd58>] ? napi_skb_finish+0x38/0x40 <4>[ 924.866533] [<c03c1e86>] ? vlan_gro_receive+0x76/0x80 <4>[ 924.867055] [<f05adba4>] ? e1000_receive_skb+0x74/0x80 [e1000] <4>[ 924.867571] [<f05b2b67>] ? e1000_clean_rx_irq+0x1f7/0x3e0 [e1000] <4>[ 924.868084] [<f05b2970>] ? e1000_clean_rx_irq+0x0/0x3e0 [e1000] <4>[ 924.869025] [<f05b06ac>] ? e1000_poll+0x4c/0x1f0 [e1000] --snip-- Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com>

2013-06-24acinclude: Improve detection of not-understood compiler options with clang.Ben Pfaff
By default, clang warns about but does not fail on unknown -W options. This made configure add the option to WARNING_FLAGS, which caused the warning about not-understood warnings to be emitted for every file compiled. In combination with -Werror, clang does fail on unknown -W options. This commit adds -Werror during configure's warning tests, which should cause the not-understood warnings to be detected that way.
