[PATCH] rpc: Re-read the data if EAGAIN or EINTR were captured
by yong.huang＠smartx.com 11 Apr '25

11 Apr '25

From: Hyman Huang <yong.huang(a)smartx.com> If EAGAIN or EINTR are returned from the gnutls_record_recv, GNU TLS suggests calling the gnutls_record_recv once again to get the data. Refer to the following link to see details: https://www.gnutls.org/manual/html_node/Data-transfer-and-termination.html To follow this guidance, add the re-read logic in the virNetClientSetTLSSession function. This prevent the upper application, when calling the virConnectOpenAuth API, from receiving the follwoing error message: Unable to read TLS confirmation: Resource temporarily unavailable --- src/rpc/virnetclient.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c index 92933220e2..69b8cac481 100644 --- a/src/rpc/virnetclient.c +++ b/src/rpc/virnetclient.c @@ -1003,7 +1003,16 @@ int virNetClientSetTLSSession(virNetClient *client, ignore_value(pthread_sigmask(SIG_SETMASK, &oldmask, NULL)); #endif /* !WIN32 */ + reread: len = virNetTLSSessionRead(client->tls, buf, 1); + /* + * GNU TLS advises calling the function again to obtain the data if EAGAIN is returned. + * See reference: https://www.gnutls.org/manual/html_node/Data-transfer-and-termination.html + * */ + if (len < 0 && (errno == EAGAIN || errno == EINTR)) { + VIR_WARN("Try reading data from the TLS session again"); + goto reread; + } if (len < 0 && errno != ENOMSG) { virReportSystemError(errno, "%s", _("Unable to read TLS confirmation")); -- 2.27.0

[PATCH v3 0/5] Adding POWER11 CPU Support
by Narayana Murty N 11 Apr '25

11 Apr '25

This patch series introduces the necessary changes to support the power11 CPU and power11 host in libvirt. Additionally, it updates the QEMU capabilities with the latest QEMU version v10.0.0-rc2 to include power11 in the capabilities tests.During testing of v2 patches found a bug in qemu which sets wrong default cpu for pre-9.0 machines, that was fixed in qemu v10.0.0-rc2. Patch Summary: Patch 0001: tests: Pin pseries-2.7 tests to the version 7.0. Patch 0002: Fix: qemuhotplugtest Set the cpu version at source as POWER9. Patch 0003: Add capabilities test support for QEMU 10.0.0 on PPC64. Patch 0004: Add POWER11 CPU model support. Patch 0005: Add POWER11 host model support and accept case-insensitive. The corresponding patches for the Linux kernel and QEMU are already upstream. Relevant links are provided below: Linux kernel patches: 1. Linux P11 support: commit c2ed087ed35c ("powerpc: Add Power11 architected and raw mode") 2. Linux P11 KVM support: commit 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests") Qemu patches: 3.

[PATCH 0/5] qemu: respond to NETDEV_VHOST_USER_DISCONNECTED event by starting a new passt process
by Laine Stump 10 Apr '25

10 Apr '25

This brings behavior of passt+vhostuser in line with trad-passt - if the passt process is somehow terminated, libvirt will start a new passt process that qemu will connect to. You'll notice no change in behavior if your QEMU binary doesn't have the patches that add NETDEV_VHOST_USER_DISCONNECTED to qemu, but also nothing extra will fail. The requisite QEMU patches are upstream in commit 02fd9f8aeeb1 ("net: vhost-user: add QAPI events to report connection state"), which will be in upstream qemu-10.0.0.

[PATCH] esx: Accept empty "path" URI component same way as "/"
by Peter Krempa 09 Apr '25

09 Apr '25

From: Peter Krempa <pkrempa(a)redhat.com> When connecting to "esx://" URI there's code which prints a warning that the path is not "empty". The check validates that "uri->path" is "/". In case when the user uses URI such as: esx://hostname the warning is printed as well. Since there is no effective difference betweeen the two allow empty strings as well.
